Relish is a condiment made from chopped pickled vegetables — most commonly cucumbers. Standard sweet pickle relish contains added sugar as a defining ingredient. However, dill relish and other unsweetened versions made from only cucumbers, vinegar, salt, and spices can be fully compliant on Whole30.
Key Takeaways
- Relish is classified as Limited under standard Whole30 guidelines.
- Standard sweet pickle relish contains added sugar and is not compliant.
- Sugar-free dill relish with no excluded additives is compliant.
- Most commercial dill relish products still contain some added sugar — label review is required.
- Homemade relish using cucumbers, vinegar, salt, and compliant spices is fully compliant.
Classification Overview
Why Sweet Pickle Relish Is Not Compliant
Sweet pickle relish is defined by its sweetness. Added sugar — cane sugar, high-fructose corn syrup, or corn syrup — is a primary ingredient and typically appears second or third on commercial product labels. This categorically disqualifies standard sweet relish.
Dill Relish
Dill relish is made from cucumbers pickled in a vinegar brine with dill and salt, without the significant sweetener addition that characterizes sweet relish. However, commercial dill relish products vary:
- Some contain no added sugar — these are compliant
- Many add small to moderate amounts of sugar or corn syrup — these are not compliant
The label must be reviewed for each product.
Compliant Relish Ingredients
A compliant relish ingredient list contains only:
- Cucumbers
- Vinegar (distilled white, apple cider, or wine vinegar — all compliant; malt vinegar contains gluten and is excluded)
- Salt
- Spices: dill, garlic, mustard seed, celery seed, onion, peppercorns
No added sweeteners in any form.
Other Relish Varieties
- Corn relish: Contains corn — excluded on Whole30
- Onion relish: Check for added sugar — many commercial versions contain it
- Tomato relish: Check for added sugar and other additives
- Pepper relish: Check for added sugar
Any relish product with added sweeteners, corn-derived ingredients, or other excluded additives is not compliant.
Homemade Relish
Homemade relish made from finely chopped cucumbers, apple cider vinegar, salt, dill, mustard seed, garlic, and optional spices — with no added sweetener — is fully compliant. The texture is coarser than commercial relish, but the flavor profile is similar to dill relish.
Use Context
Relish is commonly used in tartar sauce, egg salad, and as a condiment alongside proteins. Compliant relish allows these preparations to remain compliant when made with other verified compliant ingredients.
Summary
Relish is classified as Limited under standard Whole30 guidelines. Standard sweet pickle relish contains added sugar and is not compliant. Sugar-free dill relish made from cucumbers, vinegar, salt, and compliant spices is fully compliant. Most commercial relish products require label review as sugar is frequently added even in non-sweet varieties.
