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.
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.
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!!
