What condiments are safe to keep out on the counter, and what must go in the fridge? Generally speaking, if it has dairy, veggies or fruit in it, it must be refrigerated, and this includes things like vinaigrettes and the popular Asian sauce ponzu (because it contains citrus). Soy sauce, vinegars, oils, hot sauce and even peanut butter can be kept out, but never use the same knife to spread jelly and peanut butter onto a sandwich, as this can lead to cross-contamination and bacterial growth. Use separate knives, or always keep the PB and the J refrigerated.
