1. A capsule for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, by means of a beverage brewing device comprising a receptacle for receiving the capsule, the capsule comprising: a cup comprising a circumferential wall, a bottom closing the circumferential wall at a first end, anda lid in use connected to the cup at a second end of the circumferential wall opposite the bottom,wherein the wall, bottom and lid, in use, enclose an inner space comprising the extractable product, andwherein at least a portion of a surface of the capsule conceived to, in use, interact with the receptacle is provided with a projection for forming a sealing engagement with the receptacle;wherein the projection is integral with the cup and is made of the same material as the cup; andwherein the projection has a textured, undulating surface, wherein the textured, undulating surface includes a mixture of regularly spaced depressed and elevated areas, wherein a height difference between the elevated areas and the depressed areas is at least 0.05 mm. 2. The capsule according to claim 1, wherein the cup further comprises a flange-like rim extending outwardly of the circumferential wall at the second end, wherein the at least one projection is provided on the flange-like rim. 3. The capsule according to claim 1, wherein the at least one projection is circumferential with respect to the capsule. 4. The capsule according to claim 1, wherein the at least one projection is provided on separate regions along a periphery of the capsule. 5. The capsule according to claim 1, wherein a height of the at least one projection is defined by the undulating surface. 6. The capsule according to claim 1, wherein the at least one projection comprises a circumferential ridge. 7. The capsule according to claim 1, wherein said at least one projection is not a plurality of concentric circumferential ridges made of the same material as the cup provided on the flange-like rim. 8. The capsule according to claim 1, wherein the at least one projection is flexible. 9. The capsule according to claim 1, wherein the at least one projection is plastically deformable. 10. The capsule according to claim 1, wherein the capsule comprises a further ridge which is substantially concentrically enveloping the at least one projection, wherein a height of the further ridge is different from the height of the at least one projection. 11. The capsule according to claim 10, wherein the height of the further ridge is larger than the height of the at least one projection. 12. The capsule according to claim 10, wherein the further ridge comprises a conical section on an inner circumferential surface thereof. 13. The capsule according to claim 1, wherein the lid is connected to the cup at the second end of the circumferential wall, to the flange-like rim, and the inner space is at least partially filled with the extractable product. 14. The capsule according to claim 13, wherein the capsule is hermetically closed. 15. The capsule according to claim 13, wherein the lid and/or bottom is porous and/or comprises openings for allowing a liquid to enter and/or exit the inner space. 16. The capsule according to claim 1, wherein the capsule is disposable. 17. A method of preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the method comprising the steps of: providing a capsule according to claim 1;providing a beverage brewing device comprising a receptacle for interacting with the capsule;positioning the capsule in the receptacle such that at least one of the projections contacts at least a portion of the receptacle for forming a sealing engagement between the capsule and the receptacle;providing a fluid to the inner space of the capsule for preparing the beverage;draining the beverage from the capsule. 18. A capsule and a beverage brewing device for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, comprising: a capsule comprising:a cup comprising a circumferential wall, a bottom closing the circumferential wall at a first end, anda lid in use connected to the cup at a second end of the circumferential wall opposite the bottom,wherein the wall, bottom and lid, in use, enclose an inner space comprising the extractable product, andwherein at least a portion of a surface of the capsule conceived to, in use, interact with the receptacle is provided with a projection for forming a sealing engagement with the receptacle;wherein the projection is integral with the cup and is made of the same material as the cup; anda beverage brewing device comprising a receptacle for interacting with the capsule,wherein, in use, the at least one projection abuts against at least a portion of the receptacle such that a sealing engagement between the capsule and the receptacle is formed; andwherein the projection has a textured, undulating surface, wherein the textured, undulating surface includes a mixture of regularly spaced depressed and elevated areas, wherein a height difference between the elevated areas and the depressed areas is at least 0.05 mm. 19. The capsule and a beverage brewing device according to claim 18, wherein the receptacle is provided in a form of an enclosing member. 20. The capsule and a beverage brewing device according to claim 19, wherein the capsule comprises a further ridge which is substantially concentrically enveloping the at least one projection, wherein a height of the further ridge is different from the height of the at least one projection, wherein the further ridge is arranged to abut against an outer circumferential surface of the enclosing member. 21. The capsule and a beverage brewing device according to claim 19, wherein the lid is connected to the cup at the second end of the circumferential wall, to the flange-like rim, and the inner space is at least partially filled with the extractable product, wherein the capsule is enclosed in the enclosing member such that the at least one projection abuts against at least the portion of the enclosing member, such that a sealing engagement between the capsule and the enclosing member is formed.
