1. Cook it Longer
One of the simplest ways to thicken your orange marmalade is to cook it for a longer period. Longer cooking times allow the mixture to reduce and thicken naturally. Keep in mind that this technique may affect the taste and color of your marmalade.
2. Use Pectin
Pectin is a natural thickening agent found in fruits, including oranges. You can use commercial pectin or make your own pectin by extracting it from citrus peels. Simply boil the peels in water, strain the liquid, and add it to your marmalade. Pectin works by forming a gel-like substance, giving your marmalade the desired thickness.
3. Incorporate Cornstarch
If you prefer a quick fix to your runny marmalade, cornstarch can come to the rescue. Mix a tablespoon or two of cornstarch with a small amount of water and stir until dissolved. Add this mixture to your marmalade while it’s still hot and continue to cook for a few more minutes until it thickens. Remember to whisk constantly to avoid lumps.
4. Add Citrus Zest
In addition to enhancing the flavor of your marmalade, citrus zest also contains natural pectin. Increasing the amount of citrus zest in your recipe can help thicken your marmalade without altering the taste. Grate the zest of an extra orange or two and add it to your mixture during the cooking process.
5. Opt for Agar Agar
If you’re looking for a vegan or vegetarian option, agar agar is an excellent alternative to gelatin. Derived from seaweed, it acts as a thickener and sets marmalade beautifully. Dissolve a teaspoon of agar agar powder in a small amount of water or orange juice, then add it to your marmalade during cooking.
Thickening your orange marmalade is a simple yet crucial step to ensure a perfect consistency. Whether you choose to cook it longer, use pectin, cornstarch, citrus zest, or agar agar, these tips and techniques will help you achieve the desired thickness for your homemade marmalade. So go ahead and enjoy spreading that delicious and tangy goodness on your morning toast!
