Hi Ina, I looked all over for wheat but couldn't find any in health food shops, or in the dried grains section in stupormarkets. I looked around the farmer's market and everything. Unfortunately, I didn't have the confidence to talk to any of the farmers. And I was in a rush and running out of time. This year though, I have decided to sow half of the winter wheat seeds I harvested, and buy some spring wheat to sow later, so I have a while to shop around. I have noticed that on ethicalsupermarket they have some Suma wheatgrains for 79p/500g - quite a bit cheaper. Think I'll give that a try.
MMM, it took me forever to thresh and winnow it. I cut it down one day using an old sickle I found in the allotment skip

To get it home on my bike trailer, I wrapped it up in a towel and tried to avoid the bumps on the road. Then I stood it on its end on a shelf in the shed at home. I think you're meant to stand it like this outside to allow it to dry a bit more in the sun and wind, but we weren't allowed any sunshine, so it went in the shed. I left it a few days (in hindsight it might have been better to leave it longer, but I was too excited). Now, here's where I made life really difficult and tedious for myself: I came up with the crazy idea that cutting off the wheat heads would make things quicker and easier

Erm, I couldn't be more wrong. It took forever to do that because I hadn't stacked it very well and the heads were all at different levels. It was the first nice day in ages, so I sat on the path outside to do this.
Then OH came out. I had completely forgotten he was going to make our patio on that day. (I say patio, but it's a kind of broadening of the existing paths with matching concrete so that we can fit a table on it.) So I had to gather it all up again and take it into the kitchen.
Well to cut a long story short, with OH doing the patio, I was not only trying to thresh and winnow the wheat, but I was helping him out when needed - including having to whizz up to B&Q for another 5 bags of concrete for him - and look after LO, and do all the other mundane stuff like making lunch, emptying the dishwasher, sorting the washing (which I'd just hung out when he started and I had to bring in again because it was getting covered with dust

Did I say it was the first nice day in ages?), that sort of thing. So it took me all day Friday and half of Saturday to do it, which is why I didn't get to eat the bread until late on the Saturday night.
To thresh it, I put it in a pillowcase and banged it against two walls. There's a narrow bit between my house and brick shed, so I could swing it backwards and forwards hitting both walls.
To winnow it, I poured it from one bowl to another. I tried to use the wind to blow away the chaff, but every time I went outside the wind stopped. I tried blowing it myself, but apart from getting absolutely covered in the stuff, I started to go dizzy after about 10 minutes. So unfortunately, I ended up standing the electric fan on the doorstep and using that.
To grind it up, I could have used my pestle and mortars, but despite having lots of them, none of them are anywhere near big enough. Same goes for my little coffee grinder, which doesn't grind things very fine anyway. So I cheated and put it in the electric blender. I don't think the blender was too happy with that. It worked, but it got quite warm, which apparently spoils the flavour a bit.
So I did it. Not very successfully, and not very green-ly, but I did it. I will try again, as I say, and will compare winter and spring wheat. I'm also thinking of putting a flour mill on my Christmas list

and am on the lookout for a decent basket for winnowing, because the smooth surface of the bowls I used didn't help remove the little bits of chaff at all. I'm quite pleased with my first attempt. I don't think I can call it a success, but it wasn't a failure either. Most importantly, I have learned a lot. And that's what it's all about.

Thanks Old Tree Man, you answered while I was typing all this.
