Add the salt pork, onion and cayenne; bring to a boil. Reduce to simmer, and cook uncovered for 1-1/2 to 2 hours, or until thickened and creamy. Do not allow to boil. Stir in the bacon fat or butter, taste and season as needed with salt, pepper and Cajun seasoning.
Pay extra attention to your iron intake if you follow a vegan diet, since you rely solely on non-heme iron. Be aware that your body does not absorb non-heme iron as well as it does heme. Focus on plant-based foods with the highest iron content so that you can increase your ferritin levels. Broccoli, asparagus and dark leafy greens such as spinach, collards and kale are the richest iron sources among vegetables, while lima beans and kidney beans are iron-rich legumes.
Dark green leafy vegetables and beets tend to be among the foods highest in natural nitrates. If trying to increase your nitrate intake, eating arugula, celery, lettuce, beets, spinach, watercress and chervil are good options as they contain more than 250 milligrams of nitrates per 100 grams, or 3.5 ounces.trawberries and melons are the fruits that help you produce the most nitric oxide, and other fruits, including raspberries, cherries, bananas, raisins, prunes and figs, also provide some nitric oxide. These are small amounts, however, with a banana providing less than 5 milligrams of nitrates in each 100-gram serving.
