Ingredients
Of course, mom always said to drink lots of fluids when you’re sick. And soup is a great way to get those fluids. Let’s also take a quick look at some of the benefits of the ingredients.
Ginger: has anti-inflammatory and antioxidant properties that can help boost the immune system, helps fight inflammation associated with the flu, and reduce the duration and symptoms of colds and flus. Ginger can also help clear a congested head and relieve nausea. And you don’t have to peel the ginger for this recipe. And be sure to try my Ginger Simple Syrup for more spicy flavor!
Cayenne: Cayenne pepper contains capsaicin, which will trigger sweat and blood flow, helping to eliminate toxins and relieve congestion, including a stuffy nose and postnasal drip. Capsaicin may help relieve pain and inflammation (even inflammation associated with arthritis). It can can stimulate the digestive system, helping to remove toxins from the body. And, it’s rich in antioxidants, including vitamin C, vitamin E, and beta carotene.
Lemons: Lemons are packed with vitamin C and will help boost your immune system and may shorten the duration of colds. They have antibacterial properties that can help prevent and treat the flu and help with a sore throat or nasal congestion.
Garlic: Garlic contains allicin (which is produced when garlic is crushed), a compound that may have antiviral effects. And garlic can kill viruses with these antiviral and anti-bacterial properties. It contains antioxidants that may help prevent colds and shorten their duration as well as helping to reduce inflammation in the body.


Storage and make ahead
Keep soup in an airtight container in the fridge for up to a week.
This soup can be made ahead of time and frozen so that all you have to do is reheat it when you aren’t feeling well.

Changes to the recipe
Soups can pretty much be anything you want, that’s one of the many reasons I love them so much. So, feel free to play around with this recipe as you like. Here are some starter ideas.
Add in some turmeric, lemongrass, black pepper, celery, cilantro, jalapeño or other chili peppers, lemongrass, onion, soy sauce, or honey before straining the broth.
Or, mix some goodies into the soup to make it more than a brothy soup. Stir in steamed bok choy, broccoli, cabbage, carrots, chopped scallions, parsley, cilantro, or shiitake mushrooms.
Make it more of a meal with nutritional yeast, shredded chicken, tofu, pasta (like udon, ramen, or a high protein chickpea pasta), won tons, or quinoa.
Change up the flavors with a bit of red curry paste or coconut milk. Add in a splash of apple cider vinegar for its healing properties.
