I absentmindedly reached for the vegetable oil instead of the shortening called for in the recipe. Will it still turn out? thanks in advance!

Probably not.a disaster. I've done this a couple of times on purpose when I was out of butter or shortening (depending on what the recipe called for). Actually, one was even better with the vegetable oil . I've also used olive oil instead of vegetable oil with no appreciable difference in taste or texture.

The recipe I use calls for oil instead of shortening. It will probably be fine.

Well it turned out fine! Maybe a little on the dense and moist side as opposed to fluffy and light, but that absolutely acceptable in my book! Thanks for the responses.
