I took photos of the little boys’ lunches before they started eating. This is what Moritz (aged 6+) had for lunch: a rissole, a lamp chop, a sausage and a little bit of rice salad. Oh, and a little blob of tomato sauce.

Please, check the following link http://www.thefoodpornographer.com/?cat=55
Casi al final de la página tenés una foto de este "blob of tomato sauce"
Literalmente "blob" significa manchón, mancha o goterón. Es justamente eso, acompañar la comida con esta salsa q tiene la particularidad de ir puesta en el plato en forma de redondel.

Hope this is what you're looking for.
Best of luck : )

Well, i got carried away!!!!!!! In your text, there is no "sauce" but "paste", which is a "concentrado de tomate". In any case, the procedure and the final result seems to be the same, wouldn't you agree?

La idea en este caso no es para acompañar una comida decorando el plato en forma de redondel o mancha, sino armar estos redondeles de salsa de tomate para luego frizarlos y no desperdicarlo, como muchas veces pasa cuando abrimos una lata o cartón y necesitamos usar mucho menos q lo q trae.
