Identify what orange juice is doing in your recipe: flavor (citrus), sweetness, or acidity (baking lift and balance).
Choose the closest match from the list: go 1:1 for tangerine/mandarin and apple juice, or use the adjusted ratios for mango puree and syrup.
If your substitute is thicker or sweeter, thin with water or dilute before measuring so the batter or glaze texture stays right.
Taste after mixing: if it feels flat, add a few drops of lemon; if it feels too sharp, add a pinch of sugar.
Use the swap immediately for drinks, or mix into batter/glaze right before baking to preserve the brightness.
