Can I substitute Dove's Bakery GF flour for potato flour?

[CharminglyOdd]

I have loads of rice flour to use up and some GF/Dairy Free guests. I don't have potato flour and don't want to buy any as I won't use it all up. I have Dove's GF and loads of rice flour. Recipe is here but involves 225g rice flour and 225 potato flour.

I was also going to use Stork cake 'butter' instead of real butter. Do you know if that's okay for a dairy free person please? AFAIK it's not a direct allergy more that dairy aggravates an underlying condition and she will eat dairy on occasion.

Thank you for any help you can give :)

I think the Dove's flour would be fine as a substitute for the potato flour. The stork in the block is dairy free, but the stork in the tub has milk in.

Block stork is fine for a dairy allergy - it's made from vegetable oil. It's what I bake with for DS3 who is anaphylactic to even the tiniest traces of milk protein.

Makes nice pastry.

I have tried subbing Dove's farm GF flour for a mix of potato and rice flour before. Results weren't great.

Should add, I cook dairy, soy, nut, GF most days as DS1 is coeliac so GF, and DS3 is severely allergic to dairy, soy & nuts.

Usually a mix of potato and rice flour in a recipe could be subbed for Dove's farm PLAIN flour, but there are a few recipes that just doesn't work for. Especially cakes seem not to cope well with the substitution.

And tub stork isn't dairy free, as Trixy says, only the block.

Cakes are particularly hard, even the same recipe doesn't work out the same every time I find.

I have a GF, dairy free, nut free, soy free Madeira cake recipe that has never gone wrong, but it has eggs in so no good for the OP, Trixie. It's soft enough not to have the texture of a brick, whilst stable enough to decorate with proper icing.

Oh eggs are fine, thanks for replies :) I will get a block of stork and try the substitute... what goes wrong, is it just texture or does the cake not rise? Texture I can cope with but anything major and I'll have to rethink.
