Give me five things to look for in a hot sauce.
1. Heat: spice is an important factor in hot sauce
 2. Saltiness: many hot sauces are fermented with salt, causing the sauce to taste spicy 
 3. Sweetness: due to the pepper or additives like sugar, some sauces will be sweeter than others
 4. Fruitiness: some pepper coming from tropical climates may taste like mango or pineapple
 5. Other additives: outside of the pepper, additives such as salt, sugar, vinegar or fermentation will affect the flavor of the pepper
