We can't. However, most people are able to get good results at the lake near the FFS at night, and we encourage egyptians to try and fish without recipe a few minutes to check they are getting some before asking for some of the recipe.
No; read the question above. The results of the first fair and second fair speaks for themselves though.
FFS's prices are rather high and have indeed risen between the two first fairs. This is due to an effort by FFS to generate a profit in order to be able to form a reserve of herbs and thus be able to cook new recipes without having to rush to the stores everytime. We believe that this is necessary to prevent food shortages on fair days, and the very close rush to buy herbs for a second recipe during the second fair re-enforce that. FFS members currently do not earn anything from the fairs save free helping of the recipe. In any cases, we believe that the value of the fishes an average fisher can bring back home after eating our recipe far exceed that of the contribution, and so far it seems the fishers agree :)
