The Aussie Sauce Bottle

you've read here about the fuss being made of the good old Aussie tradition of sauce bottles being poked into pies and pasties then squeezed to squirt some delicious tomato sauce into the food item.
Here is a googled image of the bottles that used to be seen in every café across the country, although most had a white cap if I remember correctly.

Most cafes had the red and yellow bottles, but in the same size, red for tomato sauce, yellow for mustard. Some also had the brown bottles for barbecue sauce. You can see the tiny cap on top of the spout, this was uncapped and the spout poked through the pastry of a meat pie or pasty, even sausage rolls, then the bottle squeezed to allow sauce to squirt into the pie etc. The entire cap can be screwed off for refilling and cleaning purposes.These spouts were then cleaned before being recapped after the bottles were refilled.

These days, the bottles you see here are more commonly used. Bought in the supermarkets already filled and then thrown away (landfill!) or recycled once emptied and rinsed clean.

the coloured part of the cap turns to open

here you see it is raised a little, that's the open position and sauce can now be squeezed from the bottle, of course you have to tip it upside down for the sauce to flow unless you want the erupting volcano effect. In cafes and maybe even in some homes, this spout is still poked into the pie or pasty to squeeze sauce into the food, rather than on top. It's much less messy to eat when the sauce is inside. Pies and pasties, sausage rolls too are usually hand held foods, sold hot and placed in paper bags for a quick lunch or snack at the footy games. 

the entire cap can be screwed off as you see here,

and held upside down under running water to clean it out so sauce doesn't coagulate in the spout and cause a blockage.
