Homemade Sour Mix
The Sidecar is a classic drink that has made a resurgence and that I absolutely dig! I am trying to recreate this sweet and sour delicacy with a homemade sour mix. I have the juice of 7 juicy, meyer lemons and 2 pink grapefruit in a jar ready to become sour mix...any suggestions? I'm thinking a 3 to 1 mix of the citrus juice (3) to 1 part simple syrup or sugar.
I usually do a two part juice to one part simple syrup (when the syrup is how you made it 1:1). I do prefer my s-n-s more on the tart side especially when in a cocktail. This method has worked quite well in the bars I have worked at, we typically use Naked's fresh lemon juice - which happens to be very sour for the most part. Fresh squeezed meyer lemons and grapefruits could be sweeter, so you will probably have to adjust per taste. Cheers!!
It really depends on what proportions you tend to like and how strong your simple syrup is. Personally, for sour mix, I use 1 part cirus juice to 1 part 1:1 simple syrup (ie. 1 cup water, 1 cup sugar). For a Sidecar, I find that I do like it a bit more on the sour side, and would use the basic sour mix that I have, and add a bit more lemon juice. I suppose for yours, being as you are adding pink grapefruit, that is a bit less sour and a bit more sweet and bitter. I have nothing to back this up with, but I feel like something along the lines of 2 parts lemon juice, 1 part grapefruit juice, 1 part 1:1 simple syrup might work nicely.
