I had a friend bring this over for dinner one night and it was amazing. The recipe is also incredibly easy.
16oz heavy cream
1/2 cup sugar
5 tbsp fresh lemon juice
Zest of one lemon
Bring the cream and sugar to a boil over medium-high heat, stirring until the sugar dissolves. Reduce the heat to medium and boil 3 minutes. Stir constantly, adjusting heat as needed to prevent mixture from boiling over. Remove from heat.
Stir in lemon juice and zest and let sit for 10 minutes to cool.
Stir mixture again and divide among 4 – 6 ramekins. Let sit in the fridge for at least 1 hour to overnight.
