Mr Jetta doesn't cook. He only knows how to heat things up.
After his class at Sur la Table, he's
thinking of taking another class. The one he's interested in is,
how to know which knife to use. I'm also thinking of joining him
but we have to wait till after the holidays. I always overextend
myself during this time of year and this year is worse.
