I only use a few Apps for cooking, drinks, and food, even if some are very nice indeed. Like the NYT Cooking, or the Jaime Oliver Apps, and others.
The one I use is Pepperplate, and I use it per my own customized purposes. It is practically a log of all my foods, and not just.
I also add the characteristics of condiments—like the various types of pepper (black, white, green…), the best Extra Virgin Olive Oils and purposes, I keep the drinks, and even centerpieces for the table.
When I add a particular recipe I then add notes on it as I go, and sometimes change it when I find a better methodology. Especially when it comes to complicated ones such as the Sourdough Starter (Lievito Madre).
I found that Apps tend to oversimplify an original recipe, and if sometimes that can be a plus, it is not always so. Besides, I think it is very important to know very well a recipe before attempting to simplify. Usually a search on internet or on the many books and magazines that I have works best.
Pepperplate is useful for me just to figure out ”what do I cook today..?” since pretty much everything I eat is there (except liver—Fegato alla Veneziana!), I also indulge and add my own photos when possible. Just for fun. ☺️
I do read “La Cucina Italiana” magazine, the on-line italian version; occasionally others too, but ”La Cucina” is the best for me.
Then I have just one more: Vivino. I use it to qualify all my wines. I kept the App account in English/US, therefore I get the prices in US$; I love to see how much a relatively affordable italian wine costs in the USA. 😉
Finally, to keep an eye on nutrition, the best App is MyFitnessPal; the only one with a complete database to cover both the USA and Italy (and probably other countries, but I didn’t try that).
