A process for preparing a frozen herb product, comprising:

• (a) introducing the herb into an infusion bath comprising 10 to 70% by weight of an osmotic agent at a temperature of at least about 180.degree. F. for a time sufficient to reduce the water activity coefficient of the herb to below about 0.97 and cause infusion of the osmotic agent into the herb;
• and
• (b) subsequently freezing the infused herb;
• wherein said herb has been frozen prior to said (a) introducing into said infusion bath.
