Warm a large bowl. Add sifted flour; make a well. To the well, add the yeast, 3/8 cup of the milk, sugar, and salt. Mix until the yeast has dissolved. Add eggs and beat with hands until well combined and smooth. Cover bowl and put in a warm place for 45 minutes.
After 45 minutes, add the butter and remaining 1/4 cup milk. Beat hard for a couple of minutes. Half fill 4 greased small cake molds. Cover molds and place in a warm spot for 10 minutes. Once risen, place in oven for 20 minutes. Unmold onto cake rack and allow to cool a little.
Meanwhile, make sauce.
In a saute pan, large enough to hold all the babas, combine butter and sugar over medium high heat. Add 1 tablespoon of the rum and sultanas(raisins), peel, and grapes. Stir to coat well. Place the babas into the fudge mixture. Prick lightly with a fork and turn in the sauce to coat well. Pour 2 tablespoons of rum over each baba and set alight. Serve babas with sauce and whipped cream.
