Paste and puree is the same thing!
Alas, tomato paste and tomato puree are definitely NOT the same thing Ray. Tomato paste is a more concentrated than tomato puree. It is generally thicker, darker, richer and sweeter than puree accordingly.
Confusion between the two is why I started a separate thread on the subject, some time ago, to try and clarify things:
http://www.curry-recipes.co.uk/curry/index.php?topic=4436.0 The confusion largely arises because, what Americans call "tomato paste", British call "puree"
Since hcool has raised the question, and since I specify "tomato paste" in all of my recipes, I think it is important for me to clarify what I mean by it and use.
I generally use "triple concentrated tomato paste" made by Leggo's (or similar) - see here for their tomato paste and their definition:
http://www.leggos.com.au/our-range/tomato-paste:

Other forms of tomato paste or puree can obviously be used, but the amounts may need to be varied to compensate for the different concentration of tomatos in them (e.g. you'd use more puree than paste to achieve the same depth of tomato flavour).
For further information, here are some extracts from a web search on the differences between the two:
http://www.recipetips.com/glossary-term/t--34805/tomato-paste.asp(Tomato paste is) fresh tomatoes cooked for several hours and then strained. The strained tomatoes are then cooked longer to reduce them to a thick concentrate. Tomato paste is used to thicken, add flavor and to add color to sauces or foods. Commercial tomato paste is available in cans or tubes from most grocery stores however, caution should be used when adding this to a food because adding too much may overpower the flavor or cause the taste to become too acidic. After opening tomato paste, it can be kept refrigerated for several days if it was canned, while tube paste will last for approximately a month. The difference between tomato paste, tomato puree and tomato sauce is texture and depth of flavor. The thicker the consistency the deeper the flavor.
Tomato paste is the thickest, then puree is next in consistency and tomato sauce is the thinnest.http://recipes.howstuffworks.com/fresh-ideas/dinner-food-facts/what-is-tomato-paste.htm(with tomato paste) tomatoes are first cooked for several hours to reduce moisture, are strained to remove the seeds and skin, then are cooked further to reduce them to a thick, rich concentrate.
In contrast, tomato pur?e consists of tomatoes that have been cooked briefly and strained, resulting in a thick liquid with a consistency between tomato paste and crushed tomatoes. Tomato sauce is thinner than pur?e, often includes additional seasonings, and may include extra ingredients for flavor.
http://www.ochef.com/559.htmTomato paste, or tomato concentrate, consists of tomatoes that have been cooked for several hours, strained and reduced to a thick, rich concentrate. It is generally fairly sweet. Tomato puree consists of tomatoes that have been cooked briefly and strained, resulting in a thick liquid. Tomato sauce is a somewhat thinner tomato puree, and may include seasonings and other flavorings so that it is ready to be used in other dishes or as a base for other sauces.
http://www.wisegeek.com/what-is-tomato-puree.htmTomato puree is a thick liquid made from cooked and strained tomatoes. The puree is made from whole tomatoes and generally does not include added water. The tomatoes used for puree are usually cooked for a short amount of time. Tomato puree can be made from scratch or bought off the shelf at the supermarket and is used in many tomato-based dishes around the world. Tomato puree often gets confused with other processed foods such as tomato paste or sauce.
The difference between tomato puree and paste or sauce is the added ingredients and consistency. Tomato sauce is usually thinner than puree and has spices and other vegetables added to create a ready-to-use blend.
Tomato paste can be thick puree, but the tomatoes are cooked for a much longer period of time before being crushed.http://en.wikipedia.org/wiki/Tomato_pur%C3%A9eThe definitions of tomato pur?e vary between regions. In the USA, tomato pur?e is a processed food product, usually consisting of only tomatoes, but can also be found in pre-seasoned form.
It differs from tomato sauce or tomato paste in consistency and content; tomato puree generally lacks the additives common to a complete tomato sauce,
and does not have the thicknesss of paste. In the United Kingdom, 'tomato pur?e' usually refers to what in America is known as concentrated tomato paste. In the UK passata refers to sieved uncooked tomatoes.
http://en.wikipedia.org/wiki/Tomato_pasteTomato paste is a thick paste made by add
ing sugar to ripened tomatoes with skin and seeds removed. Its most common culinary usage is to enrich the flavor of sauces. In the UK, paste is referred to as pur?e or concentrate. In the USA, tomato paste is concentrated tomato solids (no seeds or skin) and usually no added sugars or seasonings, with a standard of identity (see 21 CFR 155.191).[1] Tomato pur?e has a lower solids requirement.
I hope this clarifies things somewhat (at least as far as what it is that I use)!
