All sauces from The Smiling Cook are ready-to-use sauces of consistent quality, packaged in microwave-safe doypacks, long-lasting outside refrigeration, and without preservatives. They can be used as is, but also lend themselves to combination or personalization. Extremely suitable for use in the cold line. The bearnaise sauce stands out for its full flavor. The right balance between tarragon vinegar and the herb bouquet (tarragon, chervil, and shallots) is essential for this sauce. Also an ideal barbecue sauce, which is very well preservable au bain-marie.
