Hi there G@dge, welcome.
My wife also has the same strange ideas. Not just for corned beef, but other stuff as well such as sardines and peanut butter.
As far as I know the tins of corned beef in Philippines contain Brazil corned beef. Same as here in UK.
The tins of Sardines taste exactly the same to me. The only difference is price. Ligo are much more expensive.
Now regarding peanut butter, I can't offer any opinion at all. Can't stand the stuff.
Now where's my Marmite![]()
