To make the dressing: Put 1 bottle of beer in a small saucepan and bring to a boil. Reduce heat to medium and let it simmer until the beer is reduced by half. In a mixing bowl, put the mayonnaise, sour cream and crumbled cheese. Add 1/3 cup of the reduced beer, lemon juice, salt, and pepper, to taste. Mix well with a fork, leaving it lumpy.
To make the nuts: Toast the pecan halves in a medium-size, dry, nonstick pan until barely toasted, giving them a stir occasionally. Don't let them burn. Add a jolt, about 1/4 cup of reduced beer, the sugar, salt and chili powder. Let it bubble up, and reduce to lose the liquid and glaze the nuts. When the pan is dry and all the liquid has been absorbed or evaporated, take the pan off the heat.
Lay in one layer to cool. They will be slightly sticky, but will crisp up a bit as they cool.
From a head of Iceberg Lettuce, remove any wilted leaves on the outside, and remove the core, then slice the head into 4 equal wedges.
Drizzle the dressing over the Iceberg lettuce wedge. Put some large chunks of Stilton on top and finish the garnish with the Spicy Beer Nuts.
Put the eggs and mustard in a food processor. While running the machine, slowly drizzle in the oil until it gets very thick. Add some water, and then continue with the oil. Shift back and forth between the oil and water. When all is added, add the lemon zest, lemon juice, salt, and pepper, to taste. Set aside.
