Blueberry Lemon Curd

Prep10 min
Cook20 min
Total30 min + chilling
YieldAbout 1 1/2 cups
DifficultyAdvanced

Ingredients

  • 1 1/2 cupsfresh blueberries≈ 148 median blueberries
  • 1/3 cuplemon juice (about 2 lemons)
  • 1 tbsplemon zest
  • 3/4 cupgranulated sugar
  • 3large eggs
  • 2large egg yolks
  • 1/4 tspfine salt
  • 6 tbspcold unsalted butter, cubed

Steps

  1. Simmer the blueberries with 2 tablespoons of the lemon juice for 5 minutes, until fully burst. Press through a fine-mesh sieve and discard the solids. You should have about 1/2 cup of purée.
  2. Whisk the purée, remaining lemon juice, zest, sugar, whole eggs, yolks, and salt in a heavy saucepan — off the heat — until completely smooth.
  3. Cook over medium-low heat, stirring constantly with a spatula and scraping the corners, for 8–12 minutes.
  4. The curd is done when it coats the back of a spoon and a finger drawn through leaves a clean line, around 170°F. Do not let it boil or the eggs will scramble.
  5. Remove from heat and whisk in the cold butter a few cubes at a time until glossy.
  6. Strain once more for insurance, press plastic wrap directly onto the surface, and chill at least 4 hours. It thickens substantially as it cools.

Notes

  • Constant stirring over gentle heat is the entire technique. Walk away and you get sweet scrambled eggs.
  • If it does curdle slightly, an immersion blender will usually rescue it.
