Hello Claudette, I have seen Lingonberry's at Loblaws, you should be able to find it at specialty stores. If not here is a moch lingonberry sauce made with cranberry sauce.

MOCK LINGON SAUCE:

1 can whole-cranberry sauce
1/4 cup port wine
1 stick cinnamon
1/4 teasp. powdered allspice

Place all ingredients in saucepan. Simmer 15 min. Remove cinnamon. Serve hot or cold.
