Hawthorn berries

So, I had the chance to gather a bag of Hawthorn berries from a semi-wild spot yesterday.   a bit of searching brings up a lot about 'extract' and benefits and side-effects, but does anyone here have advice on how to eat/use a batch of actual berries?  and how to prepare/preserve?  

I've not had enough to cook with yet.  I gather you can make a sauce (like ketchup) successfully.  I quite like them raw just to munch on.  I'm looking forwards to getting berries on some larger fruiting forms.  
Hawthorne cordial was quite nice, but not as nice as elderflower....

Lucky you! Hawthorn is such a wonderful plant. I haven't found any nearby to harvest yet, so I haven't gotten to play with fresh ones. I have made tincture and tea from dried berries. Even the tincture is delicious! I bet a syrup would be amazing.

I have heard that the seeds are not safe to eat and need to be separated.
"The first thing you need to know about the Hawthorn berries is you should not eat the seeds. They contain cyanide bonded with sugar, called amygdalin. In your gut — actually small intestine — that changes to hydrogen cyanide and can be deadly." http://www.eattheweeds.com/the-crataegus-clan-food-poison-2/ This website also has several different recipes.

Yes we're lucky that hawthorne seems to grow quite well around here.  Not very much survives the free ranging sheep, but once they are past the seeding stage they do well.  I'm trying to grow a deer resistant hedge around my garden area of hawthorne and have had some berries the last few years.
I hadn't heard that hawthorne berries were poisonous, but it doesn't surprise or worry me: so are apple seeds see The Fern's webpage.  Hawthorne seeds have a much tougher coat, and a fibrous outer layer, so you are much less likely to chew or swallow them accidentally.

How about hawthorn jelly? Recipe here.
