Identify what you’re making: dipping/coating (needs firm set) vs drizzling vs baking mixture (needs foldable melt).
Choose the closest substitute from the list and use the ratio exactly (use weight if your recipe is weight-based).
Melt slowly on low heat (microwave in short bursts or double boiler) and stir until smooth.
If the coating is too thick, loosen with a small drizzle of neutral oil and re-stir until glossy.
Let it set at room temperature; for faster setting, cool briefly but avoid adding moisture.
