I've had it - its good - different but good. My mom bought it in the store and they were about 10-12 inches long and pretty big around. If yours are only 5 inches they still have a lot of growing to do.
I think my mom baked our squash and put butter on it while it was baking. I'm sure you can google some recipes for squash.
When its all cooked it looks like angel hair spaghetti (thin strands) and tastes like regular squash. I loved it. I'm working on my DH to try some different kinds of squash and spaghetti squash is one of them. So far he's being hesitant
He likes the green round butter squash, tho I got him to eat the acorn squash. He doesn't like the yellow squash; I do tho
