In small saute pan over high heat combine and simmer olive oil, garlic shallot, white wine, lemon rind and lemon juice.

Reduce to about 2 tablespoons, add cream and reduce again to 1/4 cup. (This happens very quickly, so do not leave the pan.) Reduce heat to medium and whisk in butter, 1 piece at a time, until all butter is melted and sauce is thick.

This will take no longer than 1 minute. Strain sauce; this sauce must be kept warm until serving time or it will separate. Do so in a thermos or over a pan of hot water for up to 2 hours before serving.
