Back to you at last Dougy Boy, sorry about the delay, I am hopeless at checking into the forum at the moment.
We have now had our first heavy snow days of the season, and for several days were fighting our way through snow storms, so you can imagine all the spaetzle, and other cold weather recipes, have already been dusted down and are in full use.
I always use fresh herbs but simply because they grow like weeds outside during the summer and then, in the winter, dozens of little herb pots take over the kitchen. We have simply become used to the taste, and colour, that fresh herbs seem to bring to the spatzle recipes.
I asked friends yesterday about dried herbs, because I have no experience, and was told that it is a completely different taste but equally as good. A bit like package sage and onion stuffing quite often tasting better than the 'real thing'. Well in my opinion anyway, I love it when someone brings me some packets for the celebration Christmas dinner, it is always much better than the sage and onion stuffing I make myself.
The advice I was given was to use only a little of the dried herbs, and gradually increase, or decrease, the quantity to your own taste as you repeat the recipe until it is exactly as you yourself like it. Also allow it to soak for a while in the liquid before using, this brings out the flavour and texture.
I tried your base recipe some weeks ago by the way, it was delicious, lots of compliments from all of those who got to share the meal, and requests for the recipe!
Good luck with the herb mix!
