Yes, in an uncontrolled airroaster. You have several options, from
best to worst:
1. Hack it and separate the heat from the fan, add a dimmer, variac or
PID controler to the heat
2. Reduce your dose, carefully, so you get 8 to 10 minute roasts to
the first pops of the second crack. This, of course, means you roast
less in more time, very inefficient; but it's the simplest path to a
technically good roast.
3. turn off the roaster completely for 30 seconds as you go into and
again when you exit the 1st crack; alternatively, give it cooling
shots for 10 seconds. This slows down the roast, but flattens the
taste.
