Easy!

Replace the vinegar called for in a recipe with twice as much lemon juice. Follow the rest of the recipe as usual.

Bon appétit!

lemon or pickle juice.

Answer by sha_lyn68
In that recipe I would go with dill pickle juice if you have any pickles on hand. Just be certain to cut back on the salt.
