I remember my mother serving vichyssoise at dinner parties in the early 70s. The very name made it sound ‘continental’ and the fact it was served cold made it vogueishly different. She used to tell a story about a society hostess she knew in England who ran out of chives on one occasion and in a last minute panic garnished her vichyssoise with grass clippings. Her guests weren’t fooled but they were too polite to say and she thought she’d got away with it. In fact she was the subject of much hilarious gossip for sometime afterwards.
My Vichyssoise
I’d always assumed the soup was invented in Vichy and I imagined high-ranking nazis ordering it in restaurants during the Occupation. Apparently not. According to Wiki it was created in 1917 by Louis Diat the chef at the Ritz-Carlton in New York who had fond memories of pouring cold milk into his mother’s hot leek and potato soup. A much better story.
A classic vichyssoise is the easiest soup to make – leeks, potatoes, chicken stock and cream – but my version is somewhat different and calls for an ingredient that’s not at all easy to come by. I’ve discovered that vichyssoise is a great way to make use of the whey that’s left over from a home cheese-making session. I got the idea from Katherine Mowbray who, during a course I attended, suggested using whey in soups such as leek and potato. Since I only ever make goats’ cheese, I thought I’d try to make a cold soup with goats’ milk whey. It was fantastic and, I think, quite original. The thing about a classic vichyssoise is the way it combines rustic earthiness with chilled sophistication. Substituting goats’ whey adds another dimension. It’s a subtle goatiness that’s elegant, not at all overpowering. I guess you could use cow or sheeps’ milk whey (even buffalo) and you’d get a slightly different result but – as I say – I only make goats’ cheese so other variants are untested.
I know people complain like mad if a recipe’s published and they can’t get the ingredients, so you’re not likely to see this in a magazine but if you do happen to get hold of some whey, here it is: Vichyssoise my Whey. I’ve also served it in shot glasses with a drop of cream and a snip of chives (never grass) to garnish. And if anyone does make it with whey from another type of milk, I’d love to hear about it.
Vichyssoise au Chèvre
50g butter
3 medium leeks, white part only, sliced thinly
3 medium potatoes, peeled and cut into chunks
1 teaspoon salt
white pepper to taste
1 bay leaf
1.5 litres goats’ milk whey
1 cup water
cream (or sour cream) and chives to garnish
Melt butter in a large pot and sweat leeks over medium-low heat for about 10 minutes until soft, stirring occasionally to prevent browning. Add potatoes, salt, pepper, bayleaf, whey and water. Bring to boil, reduce heat and simmer for about 30 minutes until potatoes are soft. Remove from heat. Extract bayleaf then puree soup in a blender.
Serve cold with a splash of cream or a blob of sour cream and a few snippets of chive.
Yay! Got to this when searching goat whey soup, thanks Anna! : )
