The king of sorbets! You can always judge how good a gelato maker is by the quality of their lemon sorbet.
Lemon sorbet is devilishly difficult to make properly because you are basically trying to turn water (lemon juice is virtually acidic water), which wants to freeze into a solid block, into a smooth, creamy sorbet — and not the crumbly, icy, poor excuse for a sorbet that is most often passed off as lemon sorbet (sorry, I’m being a bit harsh here, aren’t I?)
This acidity also plays havoc on the stabiliser, so balancing the correct sugar percentages and using the correct stabilisers are fundamental in perfecting this recipe.
If you can get your hands on Eureka lemons, grab a bag of them, as they are the best.
