No, pineapple is not keto friendly on its own. However, there are ways to cut down on pineapple carb count and still enjoy its fruity flavor. Is pineapple low carb?
You can also make this jelly milder by replacing part of the jalapeños with green bell pepper (e.g. 5 jalapeños to 1 medium green bell pepper). Or, for a kid-friendly version, use only green bell peppers. For an elegant variation, replace the vinegar with dry white wine.
I use a fine point permanent marker and label the lids with “Pineapple Jalapeño Jelly” and the date they were canned. If I gift the jelly, I’ll attach a pretty label to the lid as well. But, getting in the habit of labeling your lids right away, is a great idea.
However, instead of bell peppers, I wanted to use chili peppers-and maybe some onion to enhance the flavors. And instead of pectin (which I don’t have, and which isn’t that easy to get here in Finland), I decided to use gelatin to thicken the jelly.
