Ingredients

  • Heavy cream – provides a rich and creamy base
  • Sugar – sweetens and balances the lemon’s acidity
  • Lemon juice – thickens the cream and adds bright citrus flavor
  • Lemon zest (optional) – enhances aroma and depth of lemon flavor

Instructions

  1. In a saucepan, combine the cream and sugar over medium heat, stirring until sugar fully dissolves.
  2. Bring the mixture to a gentle boil and simmer for 2–3 minutes, stirring occasionally.
  3. Remove from heat and stir in the lemon juice.
  4. Let the mixture cool slightly, then pour into individual ramekins or glasses.
  5. Chill for 10 minutes uncovered, then cover and refrigerate for at least 4 hours or until set.
  6. Garnish with fresh berries, lemon zest, or whipped cream before serving.

Notes

  • Use only full-fat cream for proper setting.
  • Boil gently to avoid curdling.
  • Strain mixture for an ultra-smooth texture.
  • Chill uncovered briefly before covering for best consistency.
  • Best served cold and within 3 days of preparation.
