1 Cut The Meat Into Large Cubes. Put Them Into The Pan With The Onion, Garlic, And Salt And Cover With Cold Water. Bring The Meat To A Boil, Lower The Flame And Let It Simmer Until Just Tender - About 40-45 Minutes. Do Not Over Cook. Leave The Meat To Cool Off In The Broth. 2 Strain The Meat, Reserving The Broth, Then Shred Or Chop It Finely And Set It Aside. Let The Broth Get Completely Cold And Skim Off The Fat. Reserve The Fat. 3 Melt The Lard And Cook The Onion And Garlic, Without Browning, Until They Are Soft. 4 Add The Meat And Let It Cook Until It Begins To Brown. 5 Crush The Spices Roughly In The Molcajete And Add Them, With The Rest Of The Ingredients To The Meat Mixture. (If You Don'T Have A Molcajete, You Can Use The Blunt End Of A Pestle To Crush The Spices In A Bowl.) Cook The Mixture A Few Moments Longer. 6 Add Chopped Peach And Pear To The Mixture.7 Put The Poblano Chiles Straight Into A Fairly High Flame Or Under A Broiler And Let The Skin Blister And Burn. Turn The Chiles From Time To Time So They Do Not Get Overcooked Or Burn Right Through. (See How To Roast Chile Peppers Over A Gas Flame Tutorial Using Anaheim Chiles.) 8 Wrap The Chiles In A Damp Cloth Or Plastic Bag And Leave Them For About 20 Minutes. The Burned Skin Will Then Flake Off Very Easily And The Flesh Will Become A Little More Cooked In The Steam. Make A Slit In The Side Of Each Chili And Carefully Remove The Seeds And Veins. Be Careful To Leave The Top Of The Chili, The Part Around The Base Of The Stem, Intact. (If The Chilies Are Too Hot - Picante, Let Them Soak In A Mild Vinegar And Water Solution For About 30 Minutes.) Rinse The Chilies And Pat Them Dry. 9 Stuff The Chilies With The Picadillo Until They Are Well Filled Out. Set Them Aside On Paper Towels. 10 Remove The Thin Papery Skin From The Nuts. (Note, These Are Diana Kennedy'S Instructions. I Have Found It Virtually Impossible To Remove The Skins From The Fresh Walnuts That Come From Our Walnut Tree. The Above Photo Shows The Sauce Which Includes The Skins. I Think It Would Be Creamier Without The Skins, But What Can You Do? We Found That Blanching The Walnuts Did Not Help Get The Skin Off. Completely Cover The Walnuts With Cold Milk And Leave Them To Soak Overnight. 11 Blend All Of The Ingredients In A Blender Until They Are Smooth. To Serve To Assemble The Dish, Cover The Chilies In The Nogada Sauce And Sprinkle With Fresh Parsley Leaves And Pomegranate Seeds.
