Professional Sugar & Jam Thermometers for Consistent Results

Achieving the perfect set in jams, jellies, syrups and candies relies on accurate temperature control. Sugar and jam thermometers are calibrated on speciality scales that correspond to key cooking stages, ensuring you consistently reach the correct temperature without guesswork.

Common sugar stages include:

  • Thread (105-112°C)
  • Soft Ball (112-116°C)
  • Firm Ball (118-120°C)
  • Hard Ball (121-130°C)
  • Soft Crack (132-143°C)
  • Hard Crack (148-154°C)

Sugar & Jam Thermometers

What is a sugar and jam thermometer used for?

Sugar and jam thermometers are used to measure the temperature of boiling sugar and syrup mixtures, helping chefs reach specific cooking stages like soft ball, hard crack and jam set points.

At what temperature does jam set?

Jam typically reaches its setting point around 104–105°C. A sugar and jam thermometer helps you measure this accurately to ensure the correct texture in preserves.

What is the difference between a sweet thermometer and a sugar thermometer?

A sweet thermometer and a sugar thermometer are often the same or very similar, both measure high temperatures needed in sugar work. Some sweet thermometers include multi-stage scales for soft ball to hard crack.

Can sugar thermometers be used for other cooking?

Yes, sugar thermometers can also be useful for monitoring deep-frying oil temperatures and high-temperature cooking, provided the thermometer’s scale and range are appropriate.

Do sugar and jam thermometers need calibration?

Professional thermometers should be checked periodically for accuracy using standard methods (e.g., ice-point calibration) to ensure reliable readings in busy kitchens.
