Low-carb short crust pastry; second attempt

I had another try at this over Christmas, tweaking the proportions and the method slightly, and managed to get a pastry that would roll out, although it's still very short and crumbly.

3oz/ 75g wholemeal flour
2oz/ 50g No1 baking mix
2 1/2 oz/ 65g butter or margarine
Cold water

Use the usual method; mix the dry ingredients, rub in the fat and work in enough water to bind into a firm lump.
Add the water slowly; once the mixture will hold together in a ball check if it will roll out without falling apart.  If it's too dry it will crumble and fray into pieces before it's been rolled anywhere near thin enough.  If that happens, crumble it up and add some more water and try again.
Try to avoid adding much flour to the rolling surface.  The pastry may stick a little and need to be removed from the counter with the edge of a knife blade, but if you flour it heavily it will just get even drier and more crumbly.  Bear in mind also that you'll probably need to re-roll trimmings several times, as it doesn't roll out particularly thin.
I know all of this man-handling of the pastry would not be acceptable with regular short-crust, but it worked okay with this recipe and the results weren't leathery at all (and made more-than-okay mince pies).

No-added-sugar mince pies

1 quantity of low-carb pastry, see above
1 small tart eating apple or 1/4 of a large cooking apple
About 3 tblsp commercial mincemeat - no-added-sugar if possible (Infinity Foods make one)

Roll out pastry and use to line the cups of a shallow greased patty tin (I have an ancient 9-pan one with patterns in the bottom, probably originally intended for madelaines but fine for small tartlets).  Core and chop the apple leaving the skin on.  Fill half each pastry case with mincemeat (approx 1 tsp per case) and then top-up with chopped apple.  Re-roll the pastry trimmings again to get lids, wet these on the underside and stick down onto the bottom cases and the fruit filling; pierce a small vent in each one with the tip of a knife blade.
Bake at Gas 6/ 200C (180 in a fan oven) for 15 - 20 minutes or until just starting to brown on the edges.  They'll probably bubble over as they cook, so remove from the patty tins as soon as they are out of the oven to prevent them sticking.
In the photograph, the thing on the left is what my family always call The Lump; the leftover pastry trimmings rolled round the leftover chopped apple bits and baked.  Shame to waste them after all!

Low-carb short-crust pastry - first attempt

I've been meaning to have a go at inventing a pastry recipe for ages.  Last night I had a try, and the results were surprisingly succesful  There's room for improvement, texture-wise, and it isn't gluten-free; but it is high-fibre and low-carb (about half the carb load of regular pastry) and it made a perfectly acceptable shell for a quiche, so overall I feel that's a good start.

Ingredients

3 oz/ 75g/ 3/4 cup No 1 baking mix (recipe for that is here)
3 oz/ 75g/ 3/4 cup wholemeal flour (I'm using spelt at the moment as I like the flavour)
3 oz/ 75g butter
Cold water

Method

Method starts pretty much as normal.  Seive the flour, mix thoroughly with the baking mix and rub in the fat quickly and lightly till the mixture resembles breadcrumbs.  Add enough cold water, splash by splash, to bind the mixture together and gather it into a ball.

This is where things stopped being normal.  The lack of gluten in the baking mix meant the dough didn't have the same ability to stick together as a regular short-crust pastry would.  It took more water than a regular pastry recipe before I has a mix that would bind at all.  But then the very different kind of stickiness of the milled linseeds in the baking mix started to react to the water, and the dough suddenly became quite odd in texture - the least-unpleasant word I can find for it is slippery - and turned a rather unappetising greyish colour.

I looked at this and thought various less-polite forms of "oh bother".

I'd already prepared my quiche filling (1 onion, cooked in a little veg oil, mixed with 1 chopped fresh tomato, 2 eggs, 3 oz/ 75g grated strong cheddar, some milk, salt and pepper and 1 tsp wholegrain mustard), so I figured I'd better do my best with this mixture, and try again another time to get something that looked and behaved more like conventional short-crust pastry.  I was anticipating eating something leathery in the extreme, though.  Still, all food is food (sometimes in the world of experimental cookery you have to say this to yourself!).

I slapped a sheet of baking parchment into the tin, in case that rather wet mixture decided to stick, and then I tipped the mixture onto this, and smoothed it out and pushed it up to the sides by hand.  As the linseeds continued to absorb more of the moisture, the mixture seemed to grow stiffer and less slimey, and I was able to get a rather rough and untidy-looking case shaped.  I poured in the filling, topped it with a bit more grated cheese and stuck it in the oven at 150 degrees C (it's a fan oven by the way).

35 minutes later I took it out, and discovered that despite my worries I'd produced a perfectly succesful, robust, tasty pastry case.

I'd eaten half before I thought to take the photos...

Because the pastry was rather wet and slippery when made, I can't see how this would work for the kind of recipes where it needs to be rolled out and cut. I need to work out how to arrive at a result that is firm and holds its shape enough to treat conventionally like that.

But until it came out of the oven I fully expected to end up with a supper that tasted as if it was made of plasterboard.  So to end up with a pastry case that was crisp and flavoursome, kept its shape, and held a standard quiche filling without leaking, pleased me no end.

I'll be working on improvements to the texture and will report any successes here.
