Measurements here are pretty lax - really just go for enough brine to cover whatever it is you want to pickle. Add more sugar for sweeter pickles.
1 cup rice or apple cider vinegar
2 Tbsp. sugar (or more, if you like sweeter pickles)
1 Tbsp. coarse salt
1 garlic clove, smashed (optional)
2 tsp. pickling spice or mustard seed (or a sprig of fresh dill)
2 small cucumbers (or 4 mini ones), sliced on a slight diagonal
1In a small saucepan, bring the vinegar, sugar, salt, garlic and pickling spice to a simmer. Pour over the cucumber slices in a small bowl or jar. Cool, then refrigerate. Let them hang out for at least a day or two before you eat them.
