At the end of the first chapter of Thomas Deloney's Jack of Newbury, Jack's unnamed wife makes him a "Cawdle":
In the morning his wife rose betime, and merrily made him a Cawdle, and bringing it up to his bed side, asked him how he did?
And therefore forgiving each other all injuries past, having also tride one anothers patience, let us quench these burning coales of contention, with the sweete juyce of a faithfull kiss, and shaking hands, bequeath all our anger to the eating up of this Cawdle.
From the context, I assume a "cawdle" is some sort of dish. But what type of dish exactly?
