How does a posset thicken?

A posset thickens through a natural chemical reaction between acid and dairy fat . In this recipe, hot heavy cream is combined with lemon juice, which causes the proteins in the cream to coagulate. As the mixture chills, it firms into a smooth, pudding-like texture—no gelatin or eggs required. That’s the beauty of a no-bake lavender posset : rich texture, minimal ingredients.

How long does posset take to set?

A No-Bake Lavender Posset with Blackberries typically takes 4 hours to set in the refrigerator. For best results, let it chill overnight to ensure a firm, luxurious consistency. Be sure to let the mixture cool slightly before covering and chilling to avoid condensation that can water down the top layer.

How long does posset last in the fridge?

When stored in an airtight container or tightly covered ramekin, posset lasts up to 3 days in the fridge. The flavor and texture are best within the first 24–48 hours. Be sure to keep it refrigerated at all times and avoid freezing—it doesn’t thaw well.

How far in advance can you make posset?

This dessert is a make-ahead dream. You can prepare your no-bake lavender posset up to 2 days in advance without sacrificing flavor or structure. Just store it chilled and garnish with blackberries right before serving to keep the presentation fresh and vibrant.
