Separate egg yolk from egg white using the egg shell as a small bowl.
Place the egg yolk to a large coffee cup. Add 1 tsp sugar and blend together using a small spoon or small whisk
Add 1 serving of collagen powder. Continue whisking with your spoon until you create a silky smooth texture without any lumps.
Steam milk and pour over the egg yolk mixture. Stir together until everything is well incorporated and your milk froth turns slightly yellow.
Add a shot of expresso or your preferred coffee brew
Stir one more time to incorporate and enjoy!
Notes
Whisk Well
Make sure to whisk the egg yolk, sugar and collagen together well. Keep going until you reach a very creamy consistency. This will ensure a smooth texture and complete incorporation with your coffee
Separate the Egg Yolk Carefully
When separating the egg yolk from the egg white, do it carefully to avoid breaking the yolk. You can use the eggshell halves or an egg separator tool to gently transfer the yolk back and forth until the egg white has separated.
Save egg whites for later use
I always keep mine in a container in the fridge, and add to our scrambled eggs once every few days.
Use your favorite coffee
You can use any type of coffee brew that you like, from espresso, to instant coffee. If using cold brew coffee, make sure to pour warm milk over the egg yolk mixture first, or use hot cofee first and ice after.
Adjust the amount of sugar based on your preferences
You can also use honey or maple syrup as a variation. Note that the texture may be a little different.
Experiment with Flavors
Get creative and experiment with unique flavors and variations. You can add a dash of vanilla extract, cinnamon, or nutmeg for extra flavor. You can also try using flavored coffee syrups or extracts to customize the taste according to your preferences. Using condensed milk instead of fresh milk will make it taste more like Vietnamese coffee
Use unflavored collagen
For best results, use unflavored collagen to avoid clashing of flavors and to keep the ingredients as clean as possible.
Storage
Serve Immediately: Egg yolk coffee is best enjoyed fresh and hot. Serve it immediately after preparation to savor the rich flavors and creamy texture.
