I like to brew Avery's White Rascal Recipe as my base beer, but you can do any wheat beer as your preference. At flameout, add either two or three 14 oz packets of Goya's Passion Fruit Pulp . I can always find some at the frozen section of a Mexican market. There are other brands I have seen, but some have preservatives, so be careful.You can do the passion fruit after primary is done, but trust me, it isn't necessary. 3 packets at flameout is what I usually do, and it make a very passion fruit prominent beer. Nice and tart, and you don't need to wory about sanitation. I do it with just 2 packets if I want more of a wheat beer with passion fruit.Be careful with the yeast, it is explosive. I sometimes use the Belgian Wit yeast as recommended, but often just use Safale-06 as it is easy and never produces much sulfur.It's delicious, and a quick ferment so it is a quick way to fill an empty keg. Just be careful, or the keg will be empty again in no time
