I have a competition on sat and its a few hour drive and i have a feeling its gonna be a looong and cold day so wanted to take hot milk in a flask for my hot chocolate. :S
Never taken a flask of milk, but a family tradition for picnics in cooler weather wa a flask of "Milky Coffee" made with hot milk, it always travelled well.
OOh i love milky coffee. And i have been known to make up a flask of hot milky chocolate even when not going anywhere. For some reason it tastes better if you leave it in the flask for a while to 'stew' .yum yum yum.
