This walnut mustard is the kind of sensual spread I like to use with just about anything savory. The walnuts and fresh mustard seed are ground and mixed together into a smooth spread and go great on toast, sliced chicken or a grilled gruyere sandwich. Good enough to be served with filet mignon, it also makes a great vinaigrette--mix a spoonful into vinegar with flor de sal and telicherry peppercorns and whisk in some good French mausanne-les-alpilles for next week's salads.
