Identify whether your recipe needs fruit pieces, a jam-like swirl, or a glaze (texture match matters as much as flavor).
Start with the ratio for your chosen substitute, then adjust for sweetness: add a pinch of acid if too sweet, or a pinch of sugar if too sharp.
If using dried fruit, chop and mix with a teaspoon of your recipe liquid (juice/water) to reduce dryness and prevent sinking.
If using preserves/jam in a baked batter, stir to loosen first (warm jar 15–20 seconds) so it disperses evenly.
Bake as directed and taste the warm bite: apricot substitutes should read fruity-tart, not candy-sweet.
