Bloom your gelatin by sprinkling it over the warm water and letting it sit for 2 minutes. You'll see it absorb the water and get all puffy—that's exactly what you want. Stir gently until completely dissolved and set aside to cool just a bit. This keeps your strawberry semifreddo Italian smooth without grainy gelatin bits.

Whip your heavy cream to stiff peaks using an electric mixer on medium-high speed. This takes about 3-4 minutes total and transforms the cream into this cloud-like texture. Set the whipped cream in a separate bowl and refrigerate while you work on the eggs.

In another bowl, beat the egg whites with salt until you get soft peaks forming. Start slow, then gradually increase speed—this usually takes 2-3 minutes with an electric mixer. The whites should look pillowy and hold their shape but still be a little glossy.

Combine the egg yolks with honey and vanilla bean paste in a small bowl. Whisk them together for about 30 seconds until smooth and pale. Pour the cooled gelatin into this mixture and whisk again until everything's fully combined and uniform.

Fold the yolk mixture into your whipped egg whites very gently using a rubber spatula. Work from the center outward, turning the bowl as you go, folding for about 8-10 folds total. Keep the motions gentle so you don't deflate all those lovely peaks.

Now fold in the whipped cream in two batches into your egg mixture. Take half the cream, fold it in gently, then add the remaining cream and fold until no white streaks remain. This Italian frozen dessert base should look light, fluffy, and practically cloud-like at this point.

Finally, fold in your strawberry puree and lemon zest with the softest touches possible. You want pretty pink swirls running through, not completely blended smooth—this creates beautiful layers when you freeze it. Pour into your lined loaf pan and freeze for at least 6 hours, though overnight is better.
