Yellow Pepper Relish
Put water on to boil in a medium saucepan.Advertisement
Meanwhile, shred peppers and onions with the large-hole side of a box grater into a large bowl. Finely chop any remaining pieces of onion or pepper and add them to the bowl. Cover with the boiling water and set aside for 10 minutes. Drain in a large colander for 5 minutes (don't squeeze out any moisture).
Place the shredded vegetables, sugar, vinegar, pineapple juice concentrate, salt and chile (or jalapeno), if using, in a large saucepan. Bring to a simmer over medium-high heat, stirring occasionally. Reduce heat to medium-low and gently simmer until thickened and tender, 25 to 30 minutes. If the mixture gets too dry before the peppers are tender, add water, 2 tablespoons at a time. Refrigerate, uncovered, until chilled, about 2 hours.
Make Ahead Tip: Cover and refrigerate for up to 1 week.
