Milk, eggs, sugar, coconut extract.
Use that amount of milk (I use powdered) minus 1/2 cup or so for the volume of the eggs
add one eggs per cup of milk.
Add in a couple of more eggs (or just yolks) for richness.
It’s easier to whisk the eggs before adding to the milk.
Add sugar. A tablespoon per 1/2 cup of milk is enough.
add some coconut extract (or vanilla or almond or…) to taste.
put filled baking dishes in large baking pan, add warm water up most of the sides.
bake 45 minutes or so in 350 degree oven.
Baking time will depend upon the volume of dishes.
Pull out when lightly brown and still jiggles in the middle.
Sprinkle sugar over warm tops for a bit of a brulee effect.
It can also be put under the broiler after cold to melt and brown sugar.
