In a sauté pan over medium heat, add the butter and let melt. Add the prepared shallots and salt, sautéing until transparent, about 4 minutes. Transfer to a pitcher of a blender.
Add the mayonnaise, yogurt, malt vinegar and honey. Turn the blender on low speed and increase to high speed and slowly drizzle in the Sierra Nevada Pale Ale. Turn the speed down to low and add the poppy seeds, just to mix in, not purée them. Taste the dressing and adjust salt if needed.
Transfer to a seal-able container and refrigerate until ready to use. This dressing will keep for up to a week.
