Rose's Lime Substitute

Only without the high fructose corn syrup.

2 cups lime juice
¾ cup sugar
½ cup water

Heat water in the microwave or on the stove until almost boiling. Remove from heat. Add sugar and stir until dissolved. (You just made simple syrup.) Let cool. Mix with lime juice. Your sweetened lime juice will keep a couple of weeks in the fridge.

For future reference, or if you want to make a smaller amount, the ratio of sugar to water in simple syrup is 3:2. In sweetened lime juice, the ratio of lime juice to simple syrup is 2:1.

Same goes for making your own sour mix. Substitute lemon juice for lime juice and you’ve got homemade sour mix. It’s that easy.

NOTES:

• I'm drinking a gin gimlet as I type this.
• I recommend Hendrick's Gin for this purpose.  1:1 ratio.
• Couldn't be easier.
• I made a half batch and stored it in an 8 ounce lime juice bottle saved for this purpose.  (Plus I had enough left over for a couple drinks.)
