You mixed the dough, covered it, and two hours later the bowl looks exactly as it did
when you left it. Before starting again, it is worth working out which of the four causes
you hit — because two of them are fatal and two are not.
Fatal: the yeast was dead
An opened packet kept in a warm cupboard loses strength quickly, and there is no way
to tell by looking.
Test it before you commit: stir the yeast into warm water with a pinch
of sugar and leave it ten minutes. Live yeast foams visibly. No foam means no rise, and no
amount of waiting will change it.
Fatal: the liquid was too hot
The most common fatal mistake. Yeast dies at around 50 °C, and water that feels
“nicely hot” on the wrist is often well past that.
Aim for 35–38 °C. Without a thermometer: it should feel neutral on the
inside of your wrist, neither warm nor cool.
Fixable: the kitchen is cold
Below about 18 °C dough does not stop rising — it takes two or three times longer,
which reads as failure only because you were working to the recipe’s clock.
Move the bowl into a switched-off oven with the light on, or beside a pot of hot water,
and give it more time. Do not put it somewhere genuinely hot.
Fixable: salt landed on the yeast
Salt poured directly onto yeast draws water out of the cells and kills them on contact —
but usually only the part it touched. If the dough is rising unevenly, this is why.
Next time: mix salt into the flour first and add the yeast on the other side of the bowl.
Three slower causes
Rich dough. Sugar and fat both slow yeast down. Enriched doughs are meant
to take four to six hours — they are not broken.
Too much flour. Flour added by the cupful “until it stops sticking” makes
dough dense enough to resist rising. Sticky dough is usually correct dough.
Not enough kneading. Without developed gluten there is no structure to
hold gas. Knead until smooth and springy.
Reading the bowl
| What you see | Which cause |
|---|---|
| No movement at all after two hours | Dead yeast, or hot liquid |
| Rising, but very slowly | Cold room — wait |
| Rising on one side only | Salt hit the yeast |
| Rose, then collapsed | Over-proofed |
| Dense and heavy | Too much flour, or under-kneaded |
