- 16 fl oz of milk
- 4 egg yolks
- 2/3 cup of sugar
- 1/4 cup of all-purpose flour
- half lemon (peel) or 1 teaspoon of vanilla extract
Preparation time: 15 minutes, plus time to cool down
Step 1: In a small pan, warm up the milk almost to a boil, together with the lemon peel or the vanilla extract, whichever you decide to use. If you use the lemon zest, cut it in one long piece.
Step 2: In another medium size pan, whisk the egg yolks with the sugar and the flour until smooth and fluffy. Make sure there are no lumps.
