Basler Mehlsuppe (Basel Roasted Flour Soup)
A brown, velvety soup born from a single magical gesture: flour browned dry in a pan, then moistened with broth. Comforting and cheap, it nourished children and old scholars alike.

You see, this is the soup of my Basel childhood, the one my mother would simmer while my father prepared his sermon in the parsonage. All the secret lies in one thing: you must stir the flour over the fire without pause, patiently, until it takes on the hue of a ripe hazelnut — a moment too long and all is lost, burnt! I have always thought that such patience, that care for the right degree, is not so far from that required by calculation. Then you moisten it with good broth, let it thicken, and thank the Lord for a meal so simple and so good.

Why this dish? Euler was born in Basel in 1707 and spent his childhood and student years at the University there. This roasted flour soup, economical and nourishing, is THE quintessential Basel popular dish: it was served in every Reformed household in the city, including that of a pastor like his father Paul Euler.

How it was made : In Basel, flour was roasted in large batches in advance for storage, then diluted as needed over the days. The soup remains the indispensable specialty of Fasnacht (Basel Carnival), where it is still served in the early morning.
The contemporary twist : A splash of dry white wine deglazed in the pan after the flour, and a few rye croutons browned in butter on top.
