Instructions
- In a small sauce pan, over medium heat, dissolve sugar into lemon juice. Add zest.
- Lightly beat egg in a small/medium bowl. Whisking constantly, slowly pour lemon/sugar syrup into the egg. Beat for 2 minutes (only 1 if you're using a mixer), then transfer back into the saucepan.
- Heat over low heat, stirring constantly, until it just starts to bubble at the edges. Remove from heat and stir in vanilla.
- Transfer to a small container and store in the fridge.
