Mix together the first four ingredients in a saucepan, heat to a simmer, & taste for espresso. Whisk the egg yolks in a medium bowl, pour in hot espresso cream whilst whisking. Strain thru a wire strainer into a 1 qt. measure. Pour into 4 to 6 glass baking cups, bake 45 – 60 min. at 300 degrees F. in a water bath halfway up cups.
*Note: to avoid crusty tops place a piece of foil loosely over the top of the pan while baking.
