Example Input: I absolutely LOVE the just tomatoes tomatoe slices. I thought the bits might be good for soups etc., but they don't seem to have the same sweet flavor of the slices. I will ues these up, but go back to the slices. On the whole, a great product.

Example Input: I love lemon marmalade.  They are hard to find, and in the last few years I could not find any in the stores so I decided to buy this Lemon marmalade without being able to look at it closely.  I am attaching a couple of pictures so you can see the content not just the label.  I was looking forward to getting it so much. When the box arrived I opened it and tried the marmalade right away... but it was a huge disappointment.  First, it is no a true marmalade it is a jelly. I am attaching two pictures where you can see maybe a couple of lemon zest strips in the entire 454 gram (16 oz).  Second the jelly is soooo very sweet. There is not enough tartness I expected from a lemon marmalade. Third it had a weird texture, it left what I would describe as an oily feel in my mouth unlike any other jelly I have tried.  List of ingredients: Sugar 62g per 100g Glucose-fructose syrup Lemons Gelling Agent: Pectin, Citric Acid Acidity Regulator:Sodium Citrate Flavoring: Lemon Oil Color:Caramel E150C   Price with shipping slightly over $11.  I eat a lot of different jams. I like having jam with my tea.  I will not be able to eat this jelly with my tea because I really did not like so many things about it. I will try cooking with it, maybe it will work on a chicken as a sauce.  I am so disappointed!  8/22/11 Update Normally I would not comment on a specific seller on a product review, but I think in this case it is relevant. Enclosed with the marmalade was FoodIreland 100% satisfaction guarantee flyer with a contact email.  I contacted them over the weekend letting them know I was disappointed in the product. On Monday I received a notification of a full refund.  So if you like jellies the stellar customer service removes the risk of giving it a try.
