Measure using the correct ratio
1:1. Weigh rather than eyeball it — small errors show up much faster when replacing pesto.

Adjust the method

Taste and correct
Plant swaps are usually a little less salty and less rich than pesto. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.
Mistakes to avoid
- Swapping by volume when the recipe measures pesto by weight — check the ratio above first.
- Using a sweetened or flavoured version in a savoury recipe.
- Ignoring the method change: Add a splash of pasta water when tossing — vegan pesto is thicker and needs loosening.
- Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
