Here is a new, much requested Super juice recipe - Grapefruit! To get that signature rich flavor of grapefruit that comes from glutamic amino acid I added MSG, which of course wasn’t present in other super juice recipes. Grapefruit super juice is a bit more complicated because of the acid structure of the fruit and to mimic that in a super juice was challenging, but I am happy with how it turned out and that I can give you a recipe for this bitter fruit. Because it’s acid-adjusted, to be closer to lemon and lime, you can use it in any sour cocktail.
With the recipe, I am giving you something else too. A brand Super Juice calculator, so you don’t need to stress about that. Just add the amount of peels and the calculator will do the rest.
Grapefruit Super Juice
● Organic grapefruit
● Citric Acid - 0.8 × weight of peels
● Malic Acid - 0.2 × weight of peels
● MSG - 0.033 × weight of peels
● Water - 16.66 × weight of peels
Peel the grapefruit, weigh the peels, and put them in a jar with the calculated amounts of citric acid, malic acid, and MSG. See the formula above. Shake well and leave it at room temperature for up to two hours. This will give you “oleo citrate” which will give our juice acidity and a very potent grapefruit flavor. Transfer the oleo citrate (including the peels, of course) to a blender and add water (again see formula above). Make sure to rinse inside of a jar with water to get out all of the oleo citrate. Juice the grapefruit and add the juice into the blender as well. Blend for half a minute then strain through a cheesecloth. Bottle the Super Juice, keep it in the fridge, and use it within a week for best results. Try it in Tiki drinks, the Brown Derby, the Hemingway Daiquiri, the Paloma, or your other favorite sour cocktails.
