The béarnaise sauce excels by its rich flavour. A harmonious balance between the tarragon vinegar and the bouquet of herbs (tarragon, chervil and shallots) is essential for this sauce. Prepared without eggs and with vegetable oil, it is a lighter alternative and healthier than the classic béarnaise sauce. Although a freshly prepared bearnaise requires hard labour, this bearnaise sauce offers a rich, tasty and cost efcient alternative to the traditional béarnaise sauce. Also an ideal BBQ sauce, which is very well-preserved in the bain-marie.
