Another option if you can't get yeast but want to make bread at home, BTW folks. Back in (hyperventilates) the summer of 1988, I spent a summer as an innkeeper in the White Mountains of New Hampshire, and at the bed and breakfast one of the "signature" dishes was beer bread. This is the easiest bread recipe ever, and here it's one of my stepsons' all time favourites. It comes out a bit sweet and is great lathered in butter and jam.
Really easy. Heat oven to 375 F. Mix in a bowl 3 cups of white flour (never done this with whole wheat and am dubious, but if you try it let us know), 3 tsp. of baking powder, 1/4-1/3 a cup of sugar (depending on how sweet you like it). Mix up in a bowl. Add a can of the cheapest light beer you have. This is not the moment for fancy craft brew. Bud. Molson. Schlitz. Whatever. Add 1/3 cup of melted butter. Mix, pour into greased and floured bread pan, and cook. That's it. Easy enough a 17 year old can make it at 5 AM. Ask me how I know.
