Split baguette lengthwise, an electric carving knife will ease things.
Scoop out whites and soak them in mixture. Heap the lot onto lower half of baguette crust and cover with upper half. Cut into 4 equal parts. Put into plastic bag and leave in refrigerator for about 1 hr.
Bake in medium hot oven (or toaster oven) for 5 mins and turn over. Bake for an additional 5 mins or until crust isn't soggy anymore.
