1. A frozen carbonated beverage dispenser comprising: a pressure chamber adapted to contain a controlled amount of the frozen carbonated beverage to be dispensed as well as a controlled amount of carbonating gas;an outlet from the pressure chamber to dispense the frozen carbonated beverage;at least one inlet to the pressure chamber for the addition of at least one carbonating gas and/or replacement liquid to be frozen and carbonated to form the frozen carbonated beverage;at least one mass measurement means adapted to determine the mass of the pressure chamber with frozen carbonated beverage contained therein and determine the amount of frozen carbonated beverage in the pressure chamber; anda controller that determines a quantity of gas and/or liquid to be added to the pressure chamber at least partially determined by the measured mass to maintain a predetermined ratio of frozen carbonated beverage relative to carbonating gas in the pressure chamber. 2. A frozen carbonated beverage dispenser as claimed in claim 1, further comprising an actuation means for controlling the amount of frozen carbonated beverage to be dispensed. 3. A frozen carbonated beverage dispenser as claimed in claim 2, wherein the rate of frozen carbonated beverage being dispensed is proportional to the extent which the actuation means is actuated. 4. A frozen carbonated beverage dispenser as claimed in claim 1, wherein the mass measurement means comprises at least one load cell. 5. A frozen carbonated beverage dispenser as claimed in claim 1, further comprising a blend tank for blending the gas and/or liquid to be added to the pressure chamber. 6. A frozen carbonated beverage dispenser as claimed in claim 1, further comprising a beating means for agitating the frozen carbonated beverage. 7. A frozen carbonated beverage dispenser as claimed in claim 6, wherein the beating means comprises a scraper. 8. A frozen carbonated beverage dispenser as claimed in claim 7, wherein the scraper is adapted to scrape frozen beverage from at least one wall of the pressure chamber. 9. A frozen carbonated beverage dispenser as claimed in claim 7, wherein the scraper is adapted to stir the beverage. 10. A frozen carbonated beverage dispenser as claimed in claim 1, wherein the frozen carbonated beverage is a frozen or semi-frozen beverage. 11. A frozen carbonated beverage dispenser as claimed in claim 1, wherein the pressure chamber comprises a cooling means to moderate the temperature of the frozen carbonated beverage. 12. A method of controlling a quantity of gas and/or liquid to be added to a frozen carbonated beverage dispenser, the method comprising the steps of: measuring the mass of a pressure chamber with a frozen carbonated beverage to be outlet contained therein;determining a quantity of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage to be added to the pressure chamber at least partially determined by the measured mass; andadding the determined quantity of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage to the pressure chamber. 13. A method as claimed in claim 12, further comprising the steps of: measuring the mass of a blend tank; anddetermining an amount of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage in the blend tank. 14. A method as claimed in claim 13, wherein the determined quantity of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage being added to the pressure chamber is from the blend tank. 15. A method as claimed in claim 12, wherein the step of determining the quantity of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage to be added to the pressure chamber comprises: calculating a variation in mass of the pressure chamber with frozen carbonated beverage contained therein. 16. A method as claimed in claim 12, wherein the mass of the pressure chamber is measured by at least one load sensor. 17. A method as claimed in claim 13, wherein the mass of the blend tank is measured by at least one load sensor. 18. A method as claimed in claim 13, wherein quantities of carbonating gas and/or liquid to be frozen and carbonated to form the frozen carbonated beverage are added to the blend tank according to a predetermined ratio.
