¼tspcoarse Kosher salt(if using table salt, use half the amount)
2tbspvodka
⅔cupkey lime juice,fresh or bottled
2cupscold heavy whipping cream
6graham crackers,crumbled
Instructions
In a bowl, whisk together the sweetened condensed milk, lime zest, vanilla, salt, vodka and lime juice.
In a separate bowl, use an electric mixer to whip the cream until soft fluffy peaks form. Fold the whipped cream into the ice cream mixture.
Spread half the ice cream into a lidded, freezer-safe container with at least a 2 quart capacity. Sprinkle with half the crumbled graham crackers. Repeat with another layer of ice cream and graham crackers, and gently swirl the crackers into the ice cream.
Freeze until firm, at least 8 hours, or overnight.
Notes
Both regular lime juice and key lime juice can be used for this recipe.If the ice cream freezes too hard, let it sit out for 5-10 minutes to soften before scooping.Due to the water content in the lime juice, this ice cream can tend to be a bit icy, without the addition of the vodka. The alcohol lowers the freezing point of the mixture to help it freeze with a smoother texture. If you don't want to add the vodka, and you own an ice cream maker, I recommend churning the ice cream base in your ice cream maker before freezing it, which will also help smooth out the texture.
