What's a "sachet" of fast-action yeast

Toast

i.e., what is the equivalent in teaspoons of instant dry yeast, and also what is caster sugar?  Can regular white table sugar be substituted?  This is from Dan Lepard's sourcream sandwich bread recipe that appeared in the Guardian recently.  Looks like a yummy white sandwich bread.

Equal to a US packet or envelope of instant yeast that one would buy in a store, typically in strips of 3 envvelopes.

.25 ounce or 2 1/4 teaspoons of instant yeast.

Caster sugar is a very finely granulated white sugar. Probably the closest US equivalent is our "super fine" sugar, which usually will work as a substitute.

Yes, your regular granulated sugar will also work.

for you quick answer and also for the link to that nifty website.

A sachet of yeast is about 7 grams or about 1 1/2  to 2 teaspoons or half a tablespoon. The weight in grams can be found on the Fleischman's website. It is more accurate to use weight rather than volume.

Caster sugar is powdered sugar or very finely ground sugar.

 

Hope this helps,

Whir up some regular sugar in the blender to yield a finer grain.  I do that when I'm making Scottish shortbread.
