Identify what beet is doing in your recipe: color (pink/purple), sweetness, earthy flavor, or moisture.
Match the role: for concentrated color, use beetroot powder; for baking moisture, use roasted sweet potato; for savory depth, use pomegranate molasses or cooked red cabbage.
Use the listed ratio, then adjust: if flavor tastes flat, add salt; if it’s too sweet, add a small splash of acid (lemon or vinegar).
For texture-heavy recipes, blend or mash thoroughly so the substitute disappears instead of streaking.
