what to do with tomatoes

well after chutney and tomato sauce and roasting/packing them in olive oil, what else is there to do with all the yellow tomatoes i have? homemade ketchup of course

this photo shows them stewing before being blended and reduced to thicken the ketchup

tomato ketchup

8-12 good sized tomatoes

1 medium onion

1/2c brown sugar

2/3c cider vinegar

2tbl mustard seed

cook until thickened, blend until fine, simmer on medium heat until thickened.
