Hi Liz,
The major supermarkets should carry several brands of flour that are
just fine for making dough:
* General Mills Gold Medal "Better For Bread" flour is a strong (high
protein) flour for those breads that require it, such as bagels. I
like it for my sandwich bread, too.
* General Mills also just started selling their "Harvest King" medium
protein flour (very popular with many artisan bakeries) to the
public. It makes a great baguette. Most supermarkets (such as
Safeway) should have it.
* General Mills unbleached all purpose flour (even less protein than
Harvest King, but more than cake flour) is the most widely
available...and the best for "no knead" bread and other crusty,
rustic breads. Pillsbury's should work, too. I'd be a bit wary of
stores' private label brands--the quality may not be consistent. King
Arthur's all purpose flour has a bit more protein in it than I might
want for these rustic breads, but it might work, too.
Supermarkets also carry yeast...but at exorbitant prices. Instead go
to Costco, Smart & Final or whatever the local warehouse store is and
buy the one pound vacuum pack packages of Fermipan or SAF instant
yeast. The cost/ounce is 1/16th the cost/ounce of the little
envelopes of yeast.
A pound (about $2.60) may seem like a lot, but it stores well. Put a
little in a zip top bag and store in the refrigerator; put the rest
in another zip top bag and store in the freezer. It will last for ages.
A variety of bread improvers can be found at King Arthur's online
store: http://www.kingarthurflour.com/ under
"shop"->"ingredients"->"Bread Improvers & Conditioners" and
"shop"->"Bread Baking"->"Loaf Improvers".
But I don't think she will need any...
Hope this helps.
