One of the best steak sauces in this world! It’s super simple because it’s made using the steak drippings and either brandy or cognac. The alcoholic taste is cooked out and you’re left with an amazing sweet/savoury/creamy sauce with great depth of flavour and beautiful pops of heat from the peppercorns. Use crushed black peppercorns for spicier or canned green peppercorns for more mild heat.
Add brandy or cognac into the same skillet and let it simmer rapidly, scraping the bottom of the pan, until it has mostly reduced and you can no longer smell the harsh alcohol smell (~1 min).
Add broth, bring to simmer and let it simmer rapidly for 2 to 3 minutes or until it reduces by half.
Turn heat down to medium. Add mustard, cream and pepper, stir, then simmer for 1 1/2 to 2 minutes until it thickens (do not let it boil rapidly).
