Thought I would go with a quick post here. B and I bought a couple of “Mexican Sweet Limes” at the Sacramento Farmers’ Market on Sunday. They look like a round lemon. We decided to give them a whirl tonight with a Daiquiri. 
I even decided to break out a decent rum (Appelton Estates). I went with the basic daiquiri recipe:
- 2 oz rum
- 1 tsp superfine bar sugar
- juice of half a lime (in this case the Mexican sweet limes)
Shake with ice and strain into a cocktail glass.
Anyway, the upshot was rather disappointing. We actually tasted the sweet lime juice straight. It is neither tart nor particularly “citrusy” . Kind of an unfortunate use of good rum. We added the juice of half of a regular lime to each glass and this seemed to make them drinkable.
We’re still not sure what you would use a sweet lime for, but it’s not for daiquiris. Probably a good general rule is that a great cocktail like a daiquiri doesn’t need tinkering with.
Could you use it in the place of orange juice in a recipe? Like how sour orange can take the place of lemon.
The sweet limes are kind of weird. They are remarkably flavorless, so I don’t think they would really be a substitute for anything. We squeezed one and tasted it without any sweetening. It tasted like water with just a hint of some kind of non-descript citrus flavor. Still, it’s kind of fun to try something new.
