Wash and halve beets, wrap in foil and roast in a 400-degree oven for 40 minutes.
Once cooked, unwrap the beets and allow to cool. Peel and thinly slice.
In a small pan, combine remaining ingredients and bring to a boil briefly. Stir to dissolve honey, if used.
Arrange sliced beets in a jar or canister, pour liquid over. Cover tightly and refrigerate for a few days before serving.
