Butternut squash seeds.... a frugal step too far?

A couple of weeks ago I thought you'd all laugh at me for saving the beans out of the runnerbean plants left on my new plot.  But it seems quite a few of you save seeds from them.

Well today we've had butternut squash for tea and washed and saved the seeds. Do you think they'll grow and produce fruits next year, or shall I throw them away? 

I've only just discovered that if you just slice the squash down the centre, scrape out the stringy seedy bit you can roast the thing whole with the skin on!  I've been peeling the blighters all this time.  Some even claim to eat the skin, like a baked potato.  I sprinkled S&P on and a little dusting of cinnamon before baking for half an hour. DELISH!  I'm definitely growning these next year... has anyone had much success with squashes. x

Squashes are notoriously promiscuous, so it will be a case of maybe you'll grow something worthwhiel, may be not.

But you can raoast and eat the seeds like pumpkin seeds   

If it was a shop bought one, you are reasonably sure of growing a butternut rather than a mutant! They are grown in such big fields that there's not much chance of them crossing with anything IMO

But as the others have said, allotment or garden grown ones rarely breed true because of cross pollination.

Hadn't thought it might be a shop bought one... sorry 

The famous marrow/squash? ...the result of cross pollination 

Ive had good butternut squash coming up "wild" in the veg (wild as in I grew them the year before, and didn't clear them away until the frost split them and scattered their contents).

Perhaps not a good idea if you grow other pumpkins/squashes nearby.

We roast our butternut squash a la Jamie Oliver (Naked Chef Page 148) with
coriander seeds
Dried oregano
fennel seeds
dried red chilles
salt
pepper
garlic
olive oil.

Grind all to a paste and spread it on cut sides before roasting.
Fab-u-lous darling.
