Taste (Ta'am) Transfer: Spicy/Charif: Non-Kosher Utensils

A non-kosher fork, knife, or spoon may not be used to eat or cut spicy/charif food, such as tart pineapple. (If the food is not spicy or hot, you may use a clean, non-kosher utensil on an ad hoc basis.)
Example A non-kosher implement (fork, knife) that is stuck into a spicy/charif or salty food, such as a spicy pickle, will make that pickle non-kosher immediately.
Suggestion Cut onion, garlic, and other spicy/charif foods on a pareve board and with a pareve knife.
