Lemon varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common lemon varieties compare.

Variety	Best for
Eureka	Everyday lemon juice: reliable, widely stocked, very juicy.
Lisbon	Baking, canning, and lemonade: flavour close to Eureka, good acid.
Meyer	Desserts and dressings: sweeter and less sharp, thin-skinned.
Amalfi	Zesting and gourmet baking: intensely fragrant peel, low bitterness.

Which should I pick?

For dressings, curds, and cocktails, Eureka is the go-to: widely available and reliably juicy. No Eureka? Lisbon is nearly identical and works in any recipe that calls for lemon. Reach for Meyer in desserts where a sweeter, less sharp citrus note suits the dish.
