Does blood have any taste buds?

I have compiled some shocking evidence that seems to prove that blood doesnt have any taste buds. Over the years i have whitnessed him eating scraps from our plates such as pork chop grissle and chicken knuckles, food normally only consumed by dogs. I have compiled a list of evidence that should prove that the boy has no taste buds. Most recently, when drinking in the snooks, he and wayne bought rounds of drinks, he bought himself strongbow and wayne bought him woodpecker, im lead to believe that one of these is at the top of the sweet end of ciders while the other at the top of the dry end. surly a cider drinker could tell? Then there was the time wayne gave him a taste of his fine steak topped with cheese, blood claimed it was succulent! it was actually tomato. Then theres the fact he hates onions. but like pickled onion, and onion bahji, and onion rings, and if theres onion cooked into a meal then thats fine too! But then theres the time when the lads were all enclusive whilst in magaluf, blood couldnt get enough of those chicken burgers, he has them with chips, bread bolognaise sauce. they were actually fish cakes. Im sure there is further evidence but the should be damning enough.
