offerings are reversed, so whatever you offer should be something you consume yourself (or can give to someone else to eat)
So if somebody is telling you "Sekhmet likes this or that" but you detest it, then please don't feel obligated to offer it.
Many people offer beer or pomegranates.
Sekhmet's colours are red and white, and especially this year I would balance any red coloured offerings with white coloured offerings.
Cool water and bread are always good offerings
