Equipment Needed For This Recipe
Recipes on The Purple Pumpkin Blog use cups 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 US customary, imperial, and metric measurements in my recipes. Please note, that you can mix cup measurements with weighted measures, but never mix US customary/imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, liters, etc.,).
