Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online.





It may not include staple ingredients such as oil, salt, sugar, etc., as you’re likely to have those in your kitchen. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

  3. Slowly cook the onions down over medium heat for 45 minutes to an hour. (Total cooking time will depend on how many onions were used, the sugar content in the onions, and how old they are). Stir the onions every 5 or 10 minutes while they are cooking to prevent scorching.
