In Japan, tempura masters train as apprentices for years before they’re allowed to make the batter, much less dip and fry the freshest ingredients until they’re golden and crisp.
The trick to great tempura is keeping the batter chilled and carbonated, both which create a final dish that’s delicate, crisp, and not doughy. With your iSi Creative Whip, you’ll make tempura like a master in no time. Tip: Use fine sea salt which dissolves more quickly. Rice flour (found in Asian supermarkets) produces an even crunchier bite but all-purpose flour works just fine too. Replace part or all the water with vodka which evaporates even faster in the hot oil, producing an even crunchier crust.
