We have the cookbook from the pre Irma Temptation and made their sliders tonight. They make a shallot marmalade with sugar and vinegar that you cook down to what looks like a marmalade. Then you combine it with Dijon mustard and homemade mayonnaise. That’s the sauce. The burgers are lamb cumin coriander parsley celantro ( I spelled that wrong) and grated onions. With brioche buns from our local bakery and some arugula. Amazing.
