Each week we round up our favorite posts and recipes from our friends at The Kitchn.

This week, the Kitchn bakes plantain chips, which has all the qualities of a highly addictive snack: spicy, salty, and crispity crunchy.

Also on the Kitchn:

• Quick Recipe: Udon Soup with Bok Choy and Poached Egg: More proof to the theory that everything is better with a poached egg on top.
• Baking Tricks: How to Tell if Baking Powder Has Expired: Stir about 1/4 teaspoon of baking powder into 1/2 cup or so of very hot water—if the powder starts to bubble, it's still good.
• Ingredient Spotlight: Mustard Greens: Some people can't handle the bitterness of these greens, but to tame them, just try adding salt, spicy heat, or fat.
• Recipe: Double Chocolate Butterscotch Breakfast Muffins: There's not much breakfast about these, but it would be pretty great to start the day with one (or five).
