Select a substitute based on your dish type—water chestnuts or kohlrabi for raw, daikon for cooked, pear for fruit salads.
Peel and prepare the substitute as needed; julienne or slice to replicate jicama’s texture.
Measure the substitute using a 1:1 volume ratio to replace jicama in the recipe.
Adjust for flavor differences—skip sweetness when using celery or add citrus to pears to prevent browning.
For the DIY blend, combine equal parts water chestnuts and daikon radish, ensuring uniform size and texture.
