REC: Pickled Corn Relish inside, recipe calls for a minimum of flour to thicken:
Corn starch can lose its thickening ability in the presence of (too) much acid, and since this is a tested recipe (exactly as written) I recommend this one. It is thickened with flour.
If you make this, you can reduce or omit any of the dry spices. The amount of vinegar MAY NOT be omitted OR reduced as the vinegar is what preserves the low-acid veggies (corn, peppers, celery and onions) in this recipe. For the first time make the whole batch and see if you like it; you can give it away as gifts if there is too much.
Also, remember that the flavor will change for the better with time in the jars. So before you decide if you like it, let the sealed jars set 4 to 6 weeks and give it a taste. If you have followed proper BW bath procedures this will be good for a long time if you store it in a cool, dry, place.
Try the recipe as written and see what you think. Have fun!
