Soak raw cashews in hot water for at least 30 minutes (or overnight in cold water) to ensure they blend into a completely smooth, creamy filling without any grittiness.

Refrigerate the graham cracker crust for 15 minutes after pressing, then freeze the filled pie for at least 4 hours to achieve that perfect firm, sliceable texture that rivals traditional dairy pie.

Use fresh-squeezed key lime juice and add the zest at the very end of blending to preserve its bright, aromatic oils for an intensely authentic key lime pie taste.

Melt coconut oil before blending and ensure all ingredients are at room temperature to prevent the mixture from breaking and to achieve a silky, mousse-like consistency.

Add agave nectar gradually and taste as you go, since lime juice intensity varies; you can always add more sweetness but cannot remove it, ensuring a perfectly balanced tart-to-sweet ratio.
