Method of preparing filled pasta

Abstract: The present invention relates to a method of preparing an open pasta casing with a filling e.g. Cannelloni. An an open pasta casing having a moisture content from 30 to 60% by weight is arranged around a filling, said pasta and filling being such that the filling is retained in the pasta casing when immersed into hot or boiling water. The filled open pasta casing is heated in hot or boiling water.

Description: The present invention relates to a method of preparing an open pasta casing with a filling. In particular to the preparation for consumption of an open pasta casing having a moisture content from 50 to 60% by weight arranged around a filling. Filled pasta products such as Cannelloni or Tronchetti comprise a filling which is encapsulated in a pasta sheet. Such products are conventionally prepared by arranging the filled pasta products in a tray with a layer of sauce on the top and baking them in an oven. The sauce is a necessity in order to cook the pasta to a cooked texture. This preparation method has the disadvantage that it limits the type of sauce that may be used in the cannelloni or tronchetti meal as the sauce used will have to be able withstand oven heating. Furthermore, when these traditional pasta products are baked in a sauce, there is a tendency of the filling to run out of the pasta and to mix with the sauce leaving the pasta sheets less filled. The present invention aims to overcome the above-mentioned drawbacks and provides a new way of preparing cannelloni which allows cannelloni or similar types of products to be prepared without sauce, while retaining the well known al dente texture of the coating pasta. Cannelloni prepared in accordance with the invention may be eaten plain or with any type of sauce. Hence, the invention avoids the problem of a baked and only partly cooked hard surface on the cannelloni, as is normally the result when a cannelloni is baked without sauce. According to the invention, it has surprisingly been found that an open pasta product with a filling may withstand cooking in boiling water without opening further up or any substantially leakage of the filling, and that the open end pasta product can be prepared so that the final product has an al dente texture of the outer casing. Consequently, in a first aspect, the invention relates to a method of preparing an open pasta casing with a filling comprising providing an open pasta casing having a moisture content from 30 to 60% by weight arranged around a filling, said pasta and filling being such that the filling is retained in the pasta casing when immersed into hot or boiling water, and heating the product in hot or boiling water. In particular it has been found that it is possible to re-heat products having a tubular pasta casing around a filling wherein the diameter of the open end and length of the tube are approximately the same without any substantial leakage of the filling. It is therefore also possible to prepare a boiled cannelloni product of conventional dimension i.e. an elongated tube with a filling. Furthermore, the cannelloni according to the invention may be served with heat-sensitive sauces that do not withstand oven baking e.g. pesto sauce or mayonnaise or other cold sauces. In addition, the invention provides the advantage of a fast re-heating of the products as opposed to the re-heating conventionally done in a tray in an oven. The present invention distinguishes the preparation of well known filled pasta products such as Ravioli, Tortellini or other filled pasta shells which conventionally are prepared for consumption by re-heating or boiling the product in water, in that all these products have a closed pasta shell or casings encapsulating the filling during the re-heating or boiling. The Ravioli and Tortellini are conventionally made by enclosing a filling in a raw pasta sheet. The filled products referred to in connection with the invention all have non-closed pasta casings. In preparing the pasta casing according to the invention, the raw pasta used for the casing comprises 15 to 30% moisture. In a preferred embodiment the raw pasta comprises 20 to 24 % moisture. Pasta sheets of this type of pasta, e.g. 1 mm thick, generally require boiling from 1 to 5 minutes in order to reach the desired moisture content which gives the desired al dente texture. According to the invention it has been found that by blanching the pasta sheets so as to raise the moisture content to 30 to 60%, advantageously from 50 to 60%, open end tubes of pasta may be formed in which a filling can be deposited. At this moisture content overlapping blanched pasta sheets will adhere well to one another and forming of tubes can be done. Furthermore, when these filled tubes subsequently are subjected to further heating in water retain the filling inside the tube. It has been found that further increasing the moisture content of the pasta makes it unsuitable for making cannelloni that can retain a filling during re-heating as the filling tends to escape the more slippery pasta casing. On the other hand, also dried pasta with a low moisture content, e.g. 5 to 12%, has been found to be unsuitable for the present purpose. Firstly, the filling will tend to leak or flow from the casing during the initial immersing in water as the pasta casing is hard and does not provide sufficient friction against. Also, this type of pasta requires a longer cooking before the pasta casing reaches the desired texture and during the cooking the casing may furthermore enlarge causing an increased risk of the filling leaking. The filling may comprise various types of ingredients e.g. herbs, vegetable, cheese, meat etc. The moisture content of the filling preferably being 50 to 60%, more preferably abut 55 % moisture by weight. Examples of fillings are given in example 3 and 4, by way of example only. The pasta may be prepared from conventional flour such as Semolina, Durum, Wheat etc. Suitable recipes are given in examples 1 and 2, by way of example only. The filled pasta casings according to the invention are preferably heated for a period no longer than 6 to 7 minutes, advantageously the product is immersed in hot or boiling water from 1 to 5 minutes, most preferably form 2 to 3 minutes. The pasta may conveniently be in the form of a tube such as the pasta casing for a cannelloni. The tube may be made from an extruded pasta mass or from a sheet with overlapping ends. For example, the dimension of the tube may be the size of a conventional cannelloni that is about 75 mm long and with a diameter of 25 mm. However, it has been found that the tube does not need to be elongated, for example the filling is retained in the pasta tube even when the diameter is about the same as the length of the tube e.g. 25 mm. Generally, the thickness of the raw pasta should not be more than 1.3 mm, preferably in the range of 0.9 to 1.2 mm. The corresponding blanched pasta normally has a thickness in the range of 1.0 to 1.4 mm. This is in order to ensure a sufficient cooking during the period of immersing. If the pasta is too thick it will require longer cooking e.g. up to 15 to 20 min. with the risk of the filling leaking or escaping the pasta casing. In a preferred embodiment of the invention, the pasta and the filling comprise a gluing and coagulating agent. Said gluing and coagulating agent advantageously comprises albumen. Advantageously, the gluing and coagulating agent is egg white powder or whole eggs. It is preferred that the pasta comprises from 10 to 20 % whole egg by weight, advantageously over 15% by weight and the filling comprises at least 2% egg white powder by weight. Most preferably there is about 3% egg white powder by weight in the filling. The method for preparation of the filled but opened pasta casing according to the invention may comprise a packing step wherein the product is filled in a package and pasteurised in said package. The product may then be stored chilled or shelf stabled depending on the preservation of the product. For the preparation for consumption, the product is then removed from the package and immersed into hot or boiling water. The invention will now be further described with reference to examples: EXAMPLE 1 - Pasta dough Ingredients Percent, by weight Flour: Semolina or Durum 75% Egg white powder 3% Water 22% EXAMPLE 2 - Pasta dough Ingredients Percent, by weight Flour: Semolina or Durum 74% Whole egg 18% Water 8% EXAMPLE 3 - Spinach/Ricotta Filling Ingredients Percent, by weight Ricotta cheese 23% Spinach 15% Parmesan cheese 4% Bread crumbs 24% Egg white powder 3% Oil 4% Water 19% Flavours and spices the rest. EXAMPLE 4 - Basil/Ricotta Filling Ricotta cheese 33% Basil 5% Parmesan cheese 6% Bread crumbs 24% Egg white powder 3% Oil 3% Water 21% Flavours and spices the rest. EXAMPLE 5 - Cannelloni Cannelloni are prepared by sheeting and blanching raw pasta dough. The thickness of the blanched sheets is about 1 mm. Tubes are formed of the sheets around a mandrel by overlapping the ends of the sheets. Tube of various diameters are prepared. The tubes are filled with the fillings of example 2 and 3. The filling is extruded through the mandrel and the filled tubes are cut into appropriate lengths. The cannelloni are immersed into boiling water and cooked for 3 to 6 minutes depending on the size of the product. The cooked cannelloni are withdrawn from the water and examined. The pasta tubes with their filling were found to be intact and the texture of the pasta al dente.
