A change is as good as a holiday.
Changing of a cellular structure might change the consistency, however I'm curious as to how this might change the flavour in a negative way, apart from perception (seems we both have a keen interest in the science of cooking - nice). The top 2 restaurants in the world both freeze their seafood stock before defrosting it through muslin, so maybe you could teach them (Heston Blumenthal and Ferran Adria - the two top chefs in the world) a thing or two as to what they could be doing better?
There are few occasions where I feel the need to say this, but I reckon you're looking at too much science and not enough cooking. Even more so when you're talking about recipes for a home cook. A tomato base freezes really well, and to discourage people from cooking batches of it to freeze, for the sake of its cellular structure (which 99.9% of people couldn't tell the difference, including me) is absurd. The only issues that I'm aware of with regards to frozen stock is the fat content, which can turn rancid. However skimming the fat off the top can help considerably with this.
I know of many chefs who freeze stocks and one of the interesting things is that many chefs also freeze cooked tomatoes and defrost them through muslin to make tomato consommé, instead of passing them through defrosted. In fact I was taught this exact technique in France, during a chef's course. I never bothered to ask the reasoning as to why this is better than adding salt and leaving it overnight over a bowl, however I think the salt content might be the issue here.
For those who aren't too bothered about the cellular structure of their stocks, be sure to freeze it in proportionate bags, or in an ice-cube tray. You don't want to be stuck having to defrost an entire bottle of the stuff just to use once - you can't re-freeze it again safely...
NO.
I do not believe you.
You MUST be a Leo. No other star sign in the hocus-pocus world of astrology has this attitude.
