Since the "How to Select, Peel & Cut a Pineapple" post and video, a few subscribers wanted to know what was a good substitution for pineapple juice. Quite a few times, different cocktails call for this juice and sometimes at the store it slips the mind.
The most common trick I use is simply equal parts orange juice and apple juice. To get the proper color, just add a few drops of yellow food coloring. The orange juice adds acidity, while the apple juice adds sweetness. While the taste is not exact, this is enough to mimic the flavor of pineapple juice in drinks and recipes.
I hope this helps. Smacznego!
