Diego, in my tradition ( Armenian) rose petals are used basically to make rose petal marmelade which is a delicacy offered in special occasions. Its also as a filling to 'locum' also known as Turkish delight.
My grandmother showed me how to prepare it in my childhood. She would choose deep red roses ( that she grew specially for that) that were very fragrant i.e Crimson Glory. In my view with roses, what one does is add its fragrance to the preparation rather than its flavor. So having this in mind, there are quite a few Hybrid Tea roses that could provide it. Not all will do well in a pot. Here I grow outside: Papa Meilland, Mildred Scheel, Marcel Pagnol all which could provide that type of bloom. Other's that I've had experience with are: Mr. Lincoln, Oklakoma, Dufzauber, Canasta and Charles Mallerin. Other colours also can be very fragrant, but I have no culinary experience with them.
Could you bring inside, under shelter ( in a cool but not freezing area) part of your winter? That would widen options. Some of the red D.Austins are not so large bushes: 'William Shakespeare 2000' ; 'The Prince', 'Noble Anthony'. With Ht's I would want to know more about your winter conditions temperature wise.
