How would you like to have sour cream available on your boat without having to keep it refrigerated? Whether for dips or topping a taco, most of us love it.

Sour Cream – with No Refrigeration
Here’s a quick and easy way to make your own sour cream from ingredients that don’t have to be refrigerated.  If you can put the mixture in a cooler or refrigerator for 15 minutes, it’ll get even thicker – but it’ll work perfectly even if you don’t. Add a packet of your favorite dip mix and a bag of chips or baby carrots for a great mid-afternoon snack aboard your boat... 

As this video demonstrates, all you need is a can of “Media Crema” and a teaspoon of white vinegar, lemon or lime juice. Mix them together and you’ve got sour cream.

What’s this “Media Crema,” you’re asking? It’s very similar to half-and-half and comes in a can – but you’ll find it in with the Mexican (or Latin) foods instead of with evaporated milk in the grocery store (don’t try to substitute evaporated milk or sweetened condensed milk – they won’t work). Each can makes 1 cup – so if your favorite dip requires a pint, you’ll need two cans.
