With Peter Crouch and Jon Walters being the Potters' first-choice pairing up front this term, Jerome - a summer signing from Birmingham - has had limited game time for the Staffordshire outfit so far, making only 10 starts.
He has shown his worth by scoring three times in his last four games, though, and Pulis said of the 25-year-old: "He has been smashing.
"Cammy has been unlucky not to play more often, but Crouchy and Jon have been exceptional.
"They have really worked well together, but Cammy has done well in respect of his attitude towards training and the way he has worked in training. He has been a credit to himself."
Alongside Crouch and Walters, Jerome also has Kenwyne Jones and the fit-again Ricardo Fuller to compete with for a place in the Stoke attack at the moment, and Pulis is delighted to see such healthy competition in his forward line.
"We've needed them," said Pulis, speaking ahead of Saturday's FA Cup fourth-round trip to Derby.
"We have been fighting on four fronts and you need that. It is probably the most important place in anybody's group - the forwards.
"We have needed those players and we will need them from now until the end of the season."
Jerome was one of a trio of players who joined Stoke on transfer deadline day in August, Crouch and Wilson Palacios also completing their moves from Tottenham.
That made it five new recruits in total for the Potters during the last window - Jonathan Woodgate and Matthew Upson having been recruited earlier in the summer - as they prepared for a campaign that would take in Europa League football on top of their regular domestic commitments.
Pulis' team are still in Europe, with a last-32 tie against Valencia to come next month, but their only activity in the current window has seen a handful of squad players go out on loan and chairman Peter Coates has indicated there may not be much more happening before next Tuesday's deadline.
"We are not expecting anything, unless something falls that we like the look of," said Coates, quoted in The Sentinel.
"We have a quite a large squad, and feel we are well served with cover."
However, Pulis is not ruling anything out.
"Never believe chairmen! We'll see," Pulis said.
"We are very open to going either way. If there is an opportunity and we think it is a good one, that will never cease at this football club.
"I think there is always that little bit of room to do some business, but it has to be the right bit of business."
