Why Weight Matters More Than Volume

- Use a kitchen scale for ounces/grams (most accurate).
- Spoon and level if measuring by volume (avoid packing tightly).
- Check the jar label-some brands list weight per cup.

Common Mistakes to Avoid
- Packing too tightly: Adds extra ounces (can throw off recipes).
- Using liquid measuring cups: Stick to dry cups for accuracy.
- Ignoring texture: Chunky peanut butter weighs slightly more than creamy.
- Assuming all brands equal: Natural (oil-separated) peanut butter may weigh less.
When to Use Weight vs. Volume
Use weight (ounces/grams) for: Baking, nutrition tracking, precise recipes.
Use volume (cups) for: Quick meals, approximate servings, non-critical cooking.
