Ex Input:
I used this mix to make a 9x13 cake in a glass pan using grapeseed oil, spring water, and free range eggs.  I thought the cake had a nice flavor to it but it was not what I was expecting.  I was craving a white cake (like wedding cake) and went to my local store to find something wheat-free, gluten-free and dairy-free; I purchased this vanilla cake mix.  I think it is a very good mix.  I couldn't really taste the vanilla flavor but thought it had a nice flavor.  The cake is yellow, dense (but not like a pound cake) and texture-y like brown rice has more texture than white rice.  I thought the sweetness was just right.  I think I would purchase again but would make pineapple upside down cake with it.

I have never taken the time to write a review before, but in this case others need to be warned off. I expected to get a product similar to what I have seen in the stores, but this obviously is a replica. The sliders on the bottom of the tray that are supposed to keep the tray straight when you slide it in and out broke off before I even got it out of the package. It is not something you can fix unless you have a solder gun. Even then, it is very "sticky" pulling the tray out because there are no rollers. It is metal on metal, which does not work well without some sort of lubrication. I love Amazon, but this product is inferior at best.

I purchased this item because it was cheaper than other olive juices. i was looking for a good quality olive juice for martinis. i was pretty disappointed. the juice is very strong. i followed the instructions and put the ratio on the bottle into the shaker and made a martini. the ratio was 2 part vodka to 1 part olive juice. it was way too salty. the olive juice was over powering. i made a decent dirty martini with 2 parts vodka 1/4 part olive juice. i would not recommend this item.
