Storage Tips

Room temperature (processed) or refrigerator (natural). Lasts 3-6 months after opening.

Baking Science

50% fat, 25% protein. Natural PB separates because it lacks emulsifiers. In cookies, acts as both fat and structure, enabling flourless cookies.

Recipe Context

For nut flours: weigh to avoid dry or greasy texture swings.

For seed gels: hydration ratio directly affects binding strength.

For toppings: weight gives consistent coverage and bake color.

Common Pitfalls

  • Switching brands without re-checking weight can change texture and bake time.
  • Using volume-only measurements for dense ingredients can overshoot recipe targets.

Brand Variance & Measuring Method

Baseline reference: 1 cup peanut butter = 258g. In real kitchens, a practical range is usually 235g-281g per cup (9% band).

Why this happens: cut size, grind consistency, and oil content alter packing behavior.
