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. Staple ingredients such as oil, salt, sugar, etc., aren’t always included here as you’re likely to have those in your kitchen. The complete list of ALL ingredients with measurements is found on 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, that you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
