Slice fresh strawberries, blend them into a puree, and sieve to remove seeds. Heat a third of this puree just enough to warm it up (about 122–140°F). Stir the gelatin into it until dissolved, then combine with the rest of the cooler puree. Lastly, add lemon juice.

Bring the sugar and water to a temperature of 244–246°F, and while that’s happening, whip the egg whites until they form soft peaks. Slowly add the hot syrup to the meringue while whipping on high speed. Keep that mixer going until the mixture cools to room temp.
