I've got a huge surplus of green tomatoes and I'd like to make a pickle or relish etc.. I've looked online and in retro cookbooks, but there's such a huge variety of recipes I don't know where to start. One thing I'm incredibly put off by is the huge amount of sugar that's called for in almost all the recipes I've seen. Why do these recipes require so much sugar? I'm looking for one with little or no sugar; the more sour and savory the better. Thanks in advance.
