Be experimental on the oils. You will soon find out that the different oils make the whole drink taste entirely different. Peanut oil makes it smell like coffee and the taste is heavier (but is very potent!). Sunflower oil leaves a very light, pleasant taste. Sesame oil makes it exotic, avocado oil, almond oil, coconut oil, palm oil, flower oil and so on ... you can go on and on with the different oils. this is part of the fun. You can't really taste the oil, but you feel the flavor of it. Just make sure that the bottle says: ORGANIC, COLD-PRESSED AND UNREFINED! Those 3 attributes are what you need in a good oil.
