1 Prepare For Canning. Place Steamer Rack In The Bottom Of A Large (16-Qt) Stock Pot Or Canning Pot. Place New Or Clean Mason Jars On The Rack. Fill The Jars With Water And Fill The Pot With Just Enough Water To Come To The Top Of The Jars. Heat Water To A Simmer. Simmer For 10 Minutes. (Keep The Jars Warm While Preparing The Salsa.) Have A Kettle Half Filled With Water Ready To Boil, To Use To Sterilize The Jar Lids A Few Minutes Before Canning. 2 Roast The Anaheim Green Chile Peppers Until Blackened All Over. The Best Way To Do This Is Directly Over A Gas Flame On The Stovetop (See How To Roast Chiles Over A Gas Flame.) If You Don'T Have A Gas Cooktop You Can Broil The Chiles, Or Blister Them On A Grill. Note That It Is Not Essential That The Chile Peppers Be Cooked Through, Only That The Outer Tough Skin Is Blistered And Blackened. This Is What Will Help With Flavor. Also It Will Make It Easy To Peel The Chiles. Just Put The Chiles Near A Heat Source Until Blistered And Blackened, And Turn Them So That They Get Blackened On All Sides. Then Place The Chiles In A Brown Paper Bag (Or In A Covered Bowl), Close The Bag And Let The Chiles Steam In Their Own Heat For A Few Minutes. Then Gently Rub Off The Outer Skin And Discard. Cut Away The Stems And Remove The Seeds And Any Prominent Veins. Chop Up The Chiles And Set Aside; You Should Have 1 Cup Of Chopped Chiles. Do Not Use More Than 1 1/2 Cups Of Chopped Chiles. 3 Prepare The Tomatoes. You Want The Tomatoes Peeled, And There Are Several Ways Of Doing That. Blanching Them Is Easiest; Grilling Or Broiling Will Result In More Flavor. To Blanch Them, Score The Ends Of The Tomatoes And Place Them In Boiling Water For A Minute. If You Are Going To Grill Or Broil The Tomatoes, I Recommend Coring Them First. Grilling Is Best With Whole Plum Tomatoes; Grill Them On High Direct Heat Until Blackened In Parts And The Peels Are Cracked. Broiling Works With Any Sized Tomato. Just Cut Them In Half And Place The Cut Side Down On A Rimmed Baking Sheet Or Roasting Pan. Broil Until The Peels Are Blackened In Parts. Remove The Tomatoes (From Water, Grill Or Broiler) And Let Cool To The Touch. Remove And Discard The Peels. Cut Away Any Cores If You Haven'T Done So Already. Chop The Tomatoes Taking Care To Save Any Juices That May Come Out Of Them. Starting With 5 Pounds Of Tomatoes You Should End Up With About 8 Cups Of Chopped Tomatoes And Juices. (You Must Use At Least 7 Cups Of Tomatoes.) Place Them In A Bowl And Set Aside. 4 Put All Of The Ingredients Into A Large (8-Qt) Stainless Steel Pot. (Do Not Use Aluminum Or The Acidity Of The Sauce Will Cause The Aluminum To Leach Into The Sauce.) Bring To A Boil, Reduce To A Simmer. Cook Uncovered For About 10 Minutes. 5 While The Salsa Is Cooking, Place The Jar Lids In A Bowl And Cover With Boiling Water To Sterilize. 6 If You Want Your Salsa To Be More Smooth Than Chunky, Use An Immersion Blender To Pulse It A Few Times, Or Working In Batches Ladle About Half Of It Into A Blender And Pur
