Frequently Asked Questions

Can I use frozen zucchini for this recipe?

Using frozen zucchini is possible, but it may result in a more watery relish. Thaw and drain the zucchini thoroughly before proceeding with the recipe to avoid excess moisture that can affect the final consistency.

How do I adjust the sweetness of the relish?

If you prefer a less sweet relish, you can reduce the amount of sugar to your taste. Start by cutting it in half and taste-testing before cooking. You can also add a bit more vinegar to balance the flavors if you reduce the sugar.

Is it necessary to use both green and red peppers?

While both peppers add color and flavor, you can use just one type if that’s what you have on hand. Green peppers are slightly more bitter, while red peppers add sweetness. Choose according to your preference or availability.
