Air Sous Vide Panna Cotta with Blueberry Reduction

Silky panna cotta cooked gently at 190°F delivers custard-like creaminess without curdling. Tart blueberry reduction with lemon and fresh mint provides bright contrast to the vanilla-sweetened cream. Elegant dessert for dinner parties, special occasions, or when you want restaurant-quality results at home. The sous vide method ensures even cooking and perfect texture every time.

Tips
Bloom gelatin properly to avoid lumps. Let it absorb milk fully before warming to ensure smooth texture.
Use an immersion circulator if your oven lacks sous vide mode; set water bath to 190°F for same results.
Prepare blueberry reduction while panna cotta cooks to streamline timing and allow cooling time.
Good to Know
Covered in fridge up to 3 days. Blueberry reduction keeps separately up to 5 days in an airtight container.
Panna cotta can be made 1 day ahead. Blueberry reduction can be made 2 days ahead; reheat gently before serving.
Serve chilled in ramekins or glasses. Garnish just before serving to prevent mint from wilting. Pairs well with shortbread or light biscuits.
Common Mistakes
Do not skip gelatin blooming to avoid grainy, lumpy texture.
Do not exceed 190°F or cream will curdle and separate.
Do not unmold panna cotta too early or it will collapse; allow full 4-hour chill.
Do not overstir blueberry reduction or berries will fully disintegrate; stop when they just begin breaking down.

FAQ
Can I make this without a sous vide machine?
Yes. Heat cream to 160°F in a double boiler, add gelatin mixture, blend well, then pour into ramekins. Refrigerate 4 hours. Results differ slightly in texture but flavor remains excellent.
What if I don't have fresh blueberries?
Frozen blueberries work well when thawed; they may release more liquid. Alternatively, use blackberries, raspberries, or a mix. Reduce cooking time by 5 minutes if using softer berries.
How long does panna cotta keep in the fridge?
Covered panna cotta keeps 3 days refrigerated. Do not freeze as gelatin structure breaks down when thawed. Blueberry reduction stores separately up to 5 days.
