Who invented peanut butter?
Peanut butter as we know it today was developed through the contributions of several individuals, but it’s commonly attributed to Dr. John Harvey Kellogg, a nutritionist and physician, who patented a process for making peanut butter in 1895. Dr. Kellogg, who also co-invented corn flakes, was interested in developing nutritious foods for his patients at the Battle Creek Sanitarium in Michigan. His version of peanut butter was intended as a meat substitute for people who had difficulty chewing.
However, the idea of grinding peanuts into a paste predates Kellogg’s patent. The ancient Aztecs and Incas were known to grind peanuts into a paste-like substance, though it was different from modern peanut butter.
In 1884, Marcellus Gilmore Edson, a Canadian, received the first patent for peanut paste, which can also be considered an early form of peanut butter. His version was similar to the modern product, but it was made by milling roasted peanuts between two heated surfaces.
Ultimately, while Kellogg played a significant role in popularizing and developing the process for making peanut butter, the invention was a result of contributions from various people over time.
Peanut butter is a versatile and delicious ingredient that can be combined with various foods to create a tasty and nutritious protein shake. Here are some ingredients that blend well with peanut butter:
1. Bananas
- Why: Bananas add natural sweetness to peanut butter , a creamy texture, and a boost of potassium, making them an ideal pairing with peanut butter.
- How: Add a ripe banana to your shake for a classic peanut butter-banana flavor combo.
2. Chocolate
- Why: Chocolate and peanut butter are a classic combination. Adding cocoa powder, chocolate protein powder, or a small piece of dark chocolate gives the shake a rich, indulgent taste.
- How: Mix in 1-2 tablespoons of cocoa powder or a scoop of chocolate protein powder.
3. Oats
- Why: Oats add thickness, fiber, and complex carbohydrates, making your shake more filling and providing sustained energy.
- How: Blend in ¼ to ½ cup of rolled oats for a heartier shake.
4. Greek Yogurt
- Why: Greek yogurt adds creaminess, tanginess, and a significant protein boost to your shake, complementing the peanut butter.
- How: Add ½ cup of plain or vanilla Greek yogurt.
5. Honey or Maple Syrup
- Why: These natural sweeteners enhance the flavor of peanut butter and add a touch of sweetness without being overpowering.
- How: Drizzle in 1-2 teaspoons of honey or maple syrup.
6. Almond Milk or Dairy Milk
- Why: Milk, whether almond, dairy, or another type, provides a smooth base that enhances the creaminess of peanut butter while adding extra protein (especially dairy milk).
- How: Use 1-1½ cups of your preferred milk as the liquid base.
7. Berries
- Why: Berries like strawberries, blueberries, or raspberries add a burst of freshness, antioxidants, and a slight tartness that balances the richness of peanut butter.
- How: Toss in a handful of fresh or frozen berries.
8. Spinach
- Why: For a nutrient boost, spinach blends well with peanut butter without significantly altering the taste. It adds vitamins, minerals, and fiber to your shake.
- How: Add a handful of fresh spinach leaves.
9. Chia Seeds or Flaxseeds
- Why: These seeds add omega-3 fatty acids, fiber, and a slight nutty flavor that complements peanut butter.
- How: Mix in 1-2 tablespoons of chia seeds or ground flaxseeds.
10. Protein Powder
- Why: Adding a scoop of vanilla, chocolate, or even peanut butter-flavored protein powder can enhance the protein content and flavor of your shake.
- How: Include one scoop of your preferred protein powder.
11. Coffee
- Why: Coffee adds a rich, bold flavor that pairs well with peanut butter, making it a great option for a morning shake.
- How: Add ½ cup of brewed coffee (cooled) or a shot of espresso.
12. Cinnamon or Vanilla Extract
- Why: Cinnamon adds warmth and spice, while vanilla extract enhances the overall flavor of the shake, giving it a comforting and aromatic taste.
- How: Add a dash of cinnamon or ½ teaspoon of vanilla extract.
