A light cream-colored syrup is being poured slowly over the center of the toast, forming a glossy, smooth layer that flows toward the edges. Next to the toast, on the same plate, is a small pile of bright red strawberries with green leafy tops, adding a vibrant color contrast. The whole setup rests on a white marbled textured surface, with part of a woman’s hand holding the syrup container visible at the top right corner. Photo taken with an iphone --ar 4:5 --v 7

These ingredients are simple yet essential, each playing a vital role to give the Hong Kong Salted Egg Yolk Custard French Toast its unique taste, vibrant color, and irresistibly creamy texture.

Salted duck egg yolks: The star ingredient, providing a distinctive savory flavor and creamy texture that defines the custard.
Milk powder: Adds subtle creaminess and richness to the custard filling.

Cornstarch: Acts as a thickening agent for the custard to give it the perfect spreadable consistency.
Salted butter: Infuses the custard with a luscious buttery flavor and smooth texture; if using unsalted, just add a pinch of salt.
Powdered confectioners sugar: Balances the saltiness with gentle sweetness in the custard.

Vanilla extract: Adds a warming aromatic note to both custard and batter.
Turmeric (optional): Gives a lovely golden hue to the custard, making it visually appealing.
Milk bread slices: Thick and fluffy bread is ideal, creating the perfect sandwich base, especially if slightly stale.

Whole milk: Essential for the egg batter, adding richness and helping it soak beautifully into the bread.
Eggs: The foundation of the batter that coats the bread, creating a golden crispy crust.
Salt: Enhances the overall flavor of the batter.
Butter (for cooking): Adds flavor and helps achieve that signature golden crispiness on the outside.

Sweetened condensed milk: Used both to seal the toasts and as a luscious drizzle, adding richness and sweetness at every bite.

Directions

Step 1: Begin by preparing the custard filling. Take the salted duck egg yolks and mash them thoroughly in a small bowl with a fork until completely smooth. This step ensures there are no lumps and gives a silky texture to the filling.

Step 2: To the mashed yolks, add the milk powder and cornstarch. Mash these together until well incorporated, which helps thicken and enrich the custard.

Step 3: Now add the softened salted butter, powdered sugar, vanilla extract, and turmeric if you’re using it. Continue mashing and mixing until you get a thick, smooth custard-like paste. The turmeric gives it a beautiful golden color that makes the filling irresistible.

Step 4: Next, prepare the batter for the French toast. Whisk the eggs in a large bowl until completely mixed. Add the whole milk, salt, and vanilla extract, then whisk again until combined into a smooth liquid batter.

Step 5: Assemble the toasts by slicing each thick slice of bread almost all the way through horizontally, leaving one edge attached to create a pocket. Press down gently on the bottom half to create space inside for the filling.

Step 6: Spread a thin layer of sweetened condensed milk around the edges of the pocket to act as glue. This helps seal the sandwich and keeps the custard from leaking during cooking.

Step 7: Spoon 2 to 3 tablespoons of the salted egg yolk custard into the pocket of each piece of bread, then close and press the edges gently to seal. Set these aside as you assemble the rest.

Step 8: Heat a nonstick pan over medium heat and melt about 1 tablespoon of butter until hot and bubbling. Dip the assembled toast carefully into the egg batter, submerging both sides for about 20 seconds each.

Step 9: Lift the soaked toast gently, letting any excess batter drip off, then place it immediately in the hot pan. Cook each side for about 2 minutes or until golden brown, adjusting the heat if necessary to avoid burning. Handle the toast carefully when flipping to keep the custard sealed inside.

Step 10: Once cooked, transfer the toast to a serving plate. Continue cooking the rest of the toasts in batches, adding butter to the pan before each one if needed to keep the crust beautifully crisp and golden.

Step 11: Serve the French toast hot right away, topping each piece with an extra pat of butter and a generous drizzle of sweetened condensed milk for that signature sweet and savory combo.

Servings and Timing

This recipe makes about 4 hearty servings, perfect for sharing with family or friends. Preparation takes approximately 20 minutes, which includes making the custard filling and assembling the toasts. Cooking each batch of French toast takes around 25 minutes, bringing the total time to roughly 45 to 50 minutes from start to finish. No additional resting or cooling time is necessary since this is best enjoyed fresh and hot.

When I serve this dish, I like to keep it simple to highlight the delicious custard filling and golden toast. A little extra pat of butter melts into the hot bread beautifully, and drizzling sweetened condensed milk over the top adds a glossy, luscious finish that makes each bite feel indulgent. If you want to add a fresh touch, a few slices of ripe mango or a handful of berries on the side compliments the custard’s richness with a juicy, bright contrast.

For garnishing, I sometimes sprinkle a tiny pinch of toasted sesame seeds or finely chopped roasted nuts, which add welcome crunch and an extra layer of flavor. In terms of presentation, I arrange the toasts neatly on a warm plate so the custard stays soft and creamy. Cutting each sandwich in half diagonally reveals the beautiful yellow filling and invites everyone to dig in.

Beverage-wise, I enjoy pairing this with a lightly brewed jasmine tea or a refreshing iced lemon tea that balances the richness of the toast with a bit of subtle acidity. For more celebratory breakfasts or brunches, a glass of sparkling wine or a bubby mimosa complements the savory-sweet elements wonderfully. This recipe works perfectly for weekend mornings, special brunches, or even a cozy dinner where you want something surprisingly delightful but easy to serve.

Variations

I love experimenting with this Hong Kong Salted Egg Yolk Custard French Toast Recipe because it’s so versatile. For example, if you want to make it gluten-free, I recommend using gluten-free bread that is dense enough to hold the custard without falling apart. You can also swap whole milk for plant-based options like oat or almond milk, just know this will slightly change the richness of the batter.

If you’re interested in a vegan version, replace the butter and eggs in the batter with vegan margarine and a chickpea flour or tofu-based egg substitute. The custard filling is the trickiest to veganize because of the salted egg yolks, but you could recreate a similar texture by blending cooked pumpkin with turmeric for color, coconut cream for richness, a pinch of salt, and maple syrup for sweetness.

For a fun twist on flavor, I sometimes add a hint of cinnamon or star anise to the batter to bring a warm spice note, or incorporate finely chopped dried fruits into the custard for a pop of chewiness. Cooking-wise, while pan-frying is classic, you could also try baking the assembled toasts at about 350°F (175°C) for 10-12 minutes after battering for a less hands-on approach, just be sure to watch closely so the filling stays soft and the crust turns golden.

Storage and Reheating

Storing Leftovers

If you have leftovers, store the French toast in an airtight container in the refrigerator. I recommend placing parchment paper between each piece to prevent sticking and keep the custard from drying out. These can be safely kept for up to 2 days, though I find fresh is always best.

Freezing

You can freeze the French toast for longer storage. Arrange the cooled pieces on a baking sheet lined with parchment paper and freeze until solid, about 1-2 hours. Once frozen, transfer them to a freezer-safe airtight bag or container. They keep well for up to 1 month. Freezing preserves the custard filling and bread texture surprisingly well.

Reheating

The best way to reheat without losing that crispy exterior is to use a toaster oven or a skillet over medium-low heat. Avoid microwaving if possible, as it tends to make the bread soggy and the custard rubbery. Gently reheat each side for a couple of minutes until warm through and crisp again. You can finish with a quick drizzle of condensed milk and a dab of butter to revive the original magic.

FAQs

Can I use regular chicken eggs instead of salted duck egg yolks?

Regular chicken eggs won’t give you that signature salty richness that defines the custard. Salted duck egg yolks add a unique aroma and savory depth that really make this recipe special. If you can’t find them, try specialty Asian markets or order online.

What type of bread works best for this recipe?

I find thick slices of milk bread or slightly stale soft white bread ideal because they soak up the batter and hold the custard filling nicely without falling apart. Crusts should be removed for best texture and sealing.

Can I prepare the custard filling in advance?

Absolutely! The custard can be made a day ahead and refrigerated in an airtight container. This actually helps deepen the flavors. Just give it a quick stir before using it to fill the bread.

Is it okay to substitute sweetened condensed milk with something else?

Sweetened condensed milk is traditional here because it adds both sweetness and creaminess. If you want a substitute, try a thick honey drizzle or maple syrup, but note that this will alter the taste and texture slightly.

What’s the best way to serve leftovers?

For leftovers, I love reheating lightly in a skillet or toaster oven and adding a little fresh butter and condensed milk drizzle to bring back that fresh-from-the-pan feel. Serving warm—not hot or cold—is perfect to enjoy the soft-custard and crisp-bread contrast.
