Dynasty brand green tea is the best green tea I've ever tasted.  It never tastes stale, unlike brands I've bought in grocery stores.  This is because each tea bag is packed in a sealed envelope with a metallic lining.  The metal apparently keeps out moisture.

Ex Output:

This was my first experience of a bad Darjeeling - before, I hadn't known there was such a thing. The first brew yielded a dark rust color tinged with olive-green. The bottom of the cup was invisible. The taste was sharp and astringent. Thinking I'd brewed too long or too strong, I set the first cup aside and tried again. And then again. A light brew of 3 minutes improved the clarity; however, nothing I have tried since has removed a level of astringency and a furred taste that I associate with lesser teas. The wet leaves are the typical size, light brown but unexpectedly interspersed with limp green squares.  The aroma of dry tea in the bag reminds me of old hay - neither moldy nor spoiled, just old. In contrast, the Davidson's Keemun Conjou which arrived in the same shipment smells and tastes like delicious Keemun Conjou and nothing else.  Given the price, I knew I was gamboling and consider this a lost bet. I have given the product two stars instead of one, because I haven't thrown it out (yet). I keep a supply of Lipton's bulk tea for emergencies such as long periods of unemployment, and I don't really need more emergency tea. Perhaps it will work for iced tea.  By no means am I an expert, but I do value tea, and so I hope this opinion helps other buyers who are trying to decide between two Darjeelings. Davidson's ships quickly with value pricing, and so I am not giving up on the merchant. Just on this particular Darjeeling.

I know the product title says Molecular Gastronomy, but don't let that scare you off.  I have been looking for this for a while now, not for food science, but for something more down to earth.  I use it to make my own coffee creamer.  I have to have my coffee blonde and sweet - but the flavored creamers are full of the bad kinds of fat, and honestly, I hate to use manufactured "food" items.  I really don't think they are good for the body.  On the other hand, I hate using cold milk or cream, because I like HOT coffee.  I stumbled across this on Amazon one day and got the idea of making my own creamer.  I also bought low-fat (non-instant) milk powder and regular milk powder. The non-instant lowfat milk is a little sweeter and tastes fresher than regular instant low-fat milk, but does not dissolve good in cold water - which is not a problem for hot coffee.  You will have to play with the ratios - I would not do just the heavy cream, it made the coffee too rich. Also, I think the powder is too expensive to just use on it's own. I like mixing 1/3 of each together.  For flavoring, I bough cocoa bean powder, vanilla bean powder, and caster (superfine) sugar.  I mix up small batches along with spices like cinnamon and nutmeg to make my own flavored creamers.  If you wanted, you could use a fake sweetner powder instead.  I make up small amounts that I store in jelly canning jars. I also use my little food chopper/food processor to blend everything, so the sugar is not heavier and sinks to the bottom.  Let it settle for a bit before opening the top though.  This stuff tastes WAY better than the storebought creamers and it is fun to experiment and come up with your own flavors.  I am going to try using some essential oils next and see if I can get a good chocolate/orange mix.  All of the ingredients I mentioned are here online.  Take the time to experiment.  Maybe you don't use any low-fat milk. Or don't add any flavorings.  It is up to you.  Also, would make great housewarming/host(ess) gifts.  I am sure other molecular people will be able to tell you more of what you can do with it, and I am sure I will experiment with it in cooking - but the main reason I bought it was to make my own creamer and it worked out great.
