please remember to keep all packaging! because fluid enters the cap end at a reduced flow rate, a vacuum void would form there until the pump had time to fill it. leave to prove under a damp tea towel for 15 – 20 minutes. you may be able to swap your side for something with more nutrition like fruit or a side salad. and i promise the whole process will be a lot easier and way more fun than you ever imagined! none of them easily lend themselves to measurement.
