Hello and Happy Holidays! I own an ice cream company and am looking for some information about equipment to use for scaling large batches of caramel. Right now, we cook sugar over electric heat in an approx. 6 qt. stainless steel pot. Once the caramel is at the correct color and temp (more on that below), we add our dairy to the hot mixture. Obviously, this is not a viable option for producing large batches.
I'm familiar with confectionary equipment from Savage, but don't have the budget for an automated piece. Does anyone have experience with using just one of their copper or stainless steel kettles over a regular sized burner on electric heat? We've tried to use a single larger flat bottom pot sitting in the middle of all 4 burners on the stove to make a large batch of caramel, but it doesn't heat evenly. I'm wondering if the rounded bottom of the kettle helps the entire pot cook evenly -- would we be able to set the kettle right on the burner; or, have to use it in a double boiler setting?
Additionally, any recommendations for thermometers that work well with caramel would be welcomed. We've used digital probes and candy thermometers, but on numerous occasions, the color and smell of the caramel that we associate with "doneness" is a dramatically different temperature for each batch.
I came across a similar post on this topic from 2016, but aside from a recommendation for a large piece of equipment from Savage, there wasn't any other feedback. Hoping to get some good input that will bridge the gap between extremely small batches and mass production.
