A decaf tester?

What we need is a thermometer style stick to test coffee for absence of caffeine.

Today I bought a small decaf latte from a caterer which specifically advertised a decaf option. This was welcome - I'm not sure whether the availability of decaf is improving or whether I'm just more discerning. For instance at a motorway service station I will head for Costa or Starbucks and take a decaf into the restaurant. No point in asking there as the best I will get is a dreadfully made instant sachet. I do drink a lot of instant coffee but it needs milk.

As I came away my throat was choking and that left eye started to ache - a surefire sign that something is wrong. Apart from that I felt bright and cheerful. It was a pleasant day - and I felt quite high ... as you would after an unexpected shot of caffeine. One possibility - as I have noted before - is simply that filter decaf or whatever they use in coffee shops is not fully decaffed. Another is that staff don't always remember to get out a decaf sachet and think you won't notice.

So we need a discreet testing device. Can it be done? A device for testing for salicylate would also be handy - but a little more complex as it's not going to be found uniformly in any food. So it would have to be some kind of scanner - maybe a project for the 22nd century?

Caterers and muffins

I sent the following advice off to some caterers this week. Time will tell if I get an edible meal out of it:
It's salicylate allergy
What?
Unfortunately salicylate - much the same as aspirin - is in many fruit and vegetables, in caffeine and in most nuts, herbs and spices including pepper. The simplest solution is plain food and ungarnished vegetables with no sauces or gravy. All meats and sea food and cheese are good.


The following foods are good and commonly eaten:
Cabbage
Peas
Banana
Chocolate
Decaf coffee


Small mistakes are not fatal!


I'm not sure if I should have mentioned chocolate as I have largely given it up - but not in chocolate cake. Some supermarket chocolate muffins turned up in our house this week. I have eaten too many of them and feel unwell. I can only conclude they were stacked with loads of caffeine. This morning my left eye was sore - a sure sign of problems - and it is now spreading down my left jaw and left neck. I have taken a montelukast.

Good caterers!

I went to an event and gave them my dietary requirements. Yes, the caterers will do salicylate-free, I was told.

So there I am waiting for my dry  tuna and cheese sandwiches. Then I glance at the hot-dishes from which they are serving food. That looks good, I think. It looks like salmon, spinach and leek?

Sure enough it is. And everyone is eating a healthy salicylate-free meal. Now that's what I call good catering! Congratulations. (I wonder whether they got the idea from this site?)
