I would try these:
for recipes, use #steemkitchen and #recipe
for bread baking (JUST bread, nothing else), try #breadbakers
for sandwiches (JUST sandwiches, search the tag for the latest open contest for contest rules), you can enter the contest #steemitsandwichcontest
if you are reviewing a restaurant where other people can go and eat, use the app and tag, #letseat
Good luck! Those are what I can think of right now.
