Match the job: for thick spreads/filling, choose strained Greek yogurt, cream cheese, or crème fraîche; for dairy-free, choose cashew cream.
Prep texture first: strain yogurt, soften and beat cream cheese, or blend ricotta/cashew cream until completely smooth.
Swap using the table ratio (typically 1:1), then adjust consistency with 1–2 teaspoons water/cream as needed to reach “spreadable” thickness.
Taste-adjust: if the swap is too tangy, mix in a pinch of sugar; if it’s bland, add a tiny squeeze of lemon or a pinch of salt.
Check before committing: fold into your base and confirm it holds shape (for layered desserts) or sets (for baked fillings).
