Harvesting and Preparing Stevia Leaves
Before you can use stevia leaves, you first need to properly harvest and prepare them. The leaves are at their sweetest just before the plant begins to flower. You can use the leaves fresh, or dry them for later use. Dried leaves are often more intensely sweet than fresh ones.
To dry stevia leaves, simply harvest the branches and hang them in a warm, well-ventilated area away from direct sunlight. Once brittle, strip the leaves from the stems and store them in an airtight container, such as a mason jar, to preserve their flavor and potency.
Simple ways to use fresh or dried leaves
- Brewed Tea: Place a single fresh leaf or a few dried, crushed leaves into a mug with your favorite herbal tea. The hot water will extract the sweet glycosides, providing a calorie-free sweetness.
- Smoothies: Toss a couple of fresh stevia leaves into your blender with your smoothie ingredients to offset any bitterness from green vegetables, without adding sugar.
- Yogurt and Cereal: Crush a few dried stevia leaves and sprinkle them over your morning yogurt or oatmeal for a gentle, natural sweetness.
- Cold Drinks: Muddle a few fresh leaves into the bottom of a glass before adding ingredients for lemonade or iced tea. This releases their sweet flavor for a refreshing beverage.
Creating Your Own Stevia Extract
Making your own liquid stevia extract is a simple process that provides a concentrated, versatile sweetener. The liquid can be added to both hot and cold beverages, desserts, and sauces.
Recipe for Homemade Liquid Stevia Extract
-
Ingredients:
- 1 cup fresh or dried stevia leaves (loosely packed)
- 2 cups distilled water
-
Instructions:
- Place the leaves in a medium-sized, non-reactive pot.
- Add 2 cups of distilled water and bring the mixture to a low simmer. Avoid a rolling boil, as high temperatures can produce a bitter flavor.
- Remove the pot from the heat, cover it, and let the leaves steep for at least 30 minutes. You can increase the steeping time to 60 minutes for more potent sweetness, but be cautious of increased bitterness with prolonged steeping.
- Strain the liquid using a coffee filter or fine cheesecloth into a clean glass jar, discarding the leaves.
- Store the homemade stevia extract in the refrigerator. It typically lasts for a couple of weeks.
Baking and Cooking with Stevia Powder
For those who prefer to use stevia in powder form, you can create a simple powder from dried leaves using a coffee or spice grinder. However, it's important to remember that stevia powder is significantly sweeter than sugar and lacks sugar's bulking and caramelizing properties. This means that when baking, you will need to adjust recipes accordingly.
Tips for cooking with stevia leaves
- Start with Less: Stevia is very potent, so start by using a small amount and taste as you go. You can always add more, but you can't take away excess sweetness.
- Boost Texture: In baked goods, replacing all of the sugar with stevia can affect the texture. Try adding extra ingredients like whipped egg whites, fruit purées, or applesauce to provide the necessary bulk and moisture.
- Experimentation is Key: Baking with stevia requires some trial and error to find the right balance of sweetness and texture. Keep notes on your adjustments for future use.
