Key Ingredients & Substitutions
Fresh Cranberries: These are the star of the sauce! Fresh cranberries bring that bright, tart flavor. If fresh cranberries are unavailable, you can use frozen ones. Just don’t thaw them before cooking.
Erythritol: This is a popular keto sweetener that mimics sugar without the carbs. If you’re looking for alternatives, monk fruit or stevia can also work. Just adjust the amount according to sweetness preference, as different sweeteners vary in sweetness.
Vanilla Extract: This adds depth to the flavor. If you’re in a pinch, you can use almond extract, but use a little less as it’s more potent. I find the vanilla brings out the best in the cranberries!
Cinnamon: Adding a hint of warmth, cinnamon compliments the tartness of cranberries beautifully. For a twist, consider nutmeg or a pumpkin spice blend instead!
How Do I Make Sure My Cranberries Burst Properly?
The key to a great cranberry sauce is allowing the berries to properly burst and thicken the sauce. Here’s how:
- Start with medium-high heat to get the berries boiling. This really helps to get the bursting action going!
- Once boiling, reduce the heat to medium-low to let them simmer. Stir occasionally to prevent sticking.
- You want to cook them for about 10 to 15 minutes. Patience is vital as this duration allows the flavors to meld.
- Keep an eye on the consistency. If it’s too thick, add a little more water, and if it’s too runny, let it simmer a tad longer.
By following these steps, you’ll achieve a delicious, thick cranberry sauce every time!
