I’ve been experimenting with making citrus scrap vinegar this summer and I must say that I am hooked!
Pictured here is a batch of lemon grapefruit vinegar and it couldn’t be easier to make your own. And the best part is, it’s a great way to use up all the rinds from oranges, lemons, limes, grapefruit, or whatever citrus you have on hand. Just keep the rinds in a jar in the fridge for a couple of weeks until you accumulate enough to make a batch.
So far I’ve tried lemon, lime (my favorite so far – the flavors are complex and delicious!), orange, orange with blood orange, orange and lemon, and now grapefruit and lemon, and they are all great!
To make a batch first collect your jar of rinds, add some sugar, add some just boiled water, cover with a coffee filter kept on the jar with a rubber band, and stir daily for 4-5 days. You will see it start tomorrow bubble. When the bubbling slows down, add more sugar and stir for another week. Strain out the fruit scraps pour back into a clean jar, cover again with the coffee filter and let it sit for a month. If a opaque film develops on the surface, don’t worry, that is the vinegar mother and a good thing.
For a 1/2 gallon jar of citrus peels add 1/3 cup sugar at the first mixing, and then another 1/4 cup somewhere around day 5 or once the bubbling settles down.
For a quart jar of citrus peels add 2 tbsp sugar at the first mixing, and then another 2 tsp somewhere around day 5 or once the bubbling settles down.
After a month can test the acidity of your vinegar if you like to be sure it is acidic enough (4-5 on the pH scale) using paper test strips, or you can just taste it. If it tastes like vinegar, then it’s done! You can store it in the fridge to age and mellow it if you want or keep it in a cool, dark cupboard or your pantry as you would your other vinegars.
You can really make vinegar out of almost anything with fruit or some level of sugar content. I’ve been really enjoying this book if you want to learn more. Kirsten does a great job of explaining it ALL!
