I would suggest you find a computer to search through the site on. I have tried using this site on my mobile device and know how difficult it is. But everyone here is trying to help you and they have given you all the advice you need. There are such a wide range of aya recipes that you really have to look them over and decide for yourself what you want to try. And as far as not wanting to "waste" your whole supply, why not try finding a recipe you like and scale down so you can test it on your own. Everyone seems to favor a different recipe and it is up to you to find the one that you find the most rewarding. Suggestions to do a search for yourself is for the benefit of everyone here. A lot of us answer the same questions countless times when it is completely unnecessary. All the info you need is already on here, and if you don't find it, check erowid, they have a page with more different aya recipes than you would really need to find one that works for you. While this site is by far the best place to find the information you seek, it is not the only place where the info is available. Nobody meant to belittle you in any way. I personally avoid the addition of acid at all and just use filtered water. The tribes who use the brew don't add acid, so I choose not to. There are many people on here who would give the opposite advice, so it really is up to you to find your own method of preparation. If you are interested in this substance for the right reasons, the answers will find you, don't rush the process and always remember that you are a unique individual, and will have unique reactions to different brews.
