How to use Yum: say what you feel like, cook step by step

The situation

It is 7 pm, you have eggs, tomatoes and peppers in the fridge and one question: "what do I cook?". A blog gives you 2,000 words and "cook until done". Yum works differently: every recipe is written to the same rule (how hot the pan is, how long, at what temperature, what "done" looks like), and the AI cook answers only from those recipes, it does not make things up.

Open yum.purceas.com. No account needed.

Step 1: ask the cook

The home page has the Ask Yum box. Type what you feel like, the way you would tell a friend: "something vegetarian and filling, under 600 calories, in 30 minutes". Or tap a suggestion: What can I cook in 20 minutes?, I have eggs, tomatoes and peppers, A Romanian classic for Sunday.

The answer comes with the matching recipes as cards, with calories per serving and time. Without an account you get 5 questions a day; the recipes themselves are all open, as many as you like.

Step 2: the recipe, in detail

Open a card. On the recipe page you have:

• Servings: change the number and the quantities recalculate, calories included.
• The ingredients as a checklist and the Shopping list button.
• Every step with heat, time and degrees, plus "done when…" and the common mistakes.
• Nutrition per serving and allergens.

Step 3: cook mode

Tap Cook mode. The screen shows one step at a time, with its timer (it rings and vibrates when done), and the phone stays awake while you cook. Move to the next step with a tap or your voice: "next", "back", "repeat", "timer". At the end, I cooked this leaves a real rating and goes into your diary.

When you do not know what you want: My fridge

In My fridge you tick what you have at home. Recipes are ranked by the fewest missing ingredients, not by popularity. It is the fastest answer to "what do I make with what I have".

Eat well: a day on your calories

In Eat well you work out your daily calories (height, weight, age, activity) and Yum builds a day of meals from the library, on target. You can filter by style: Mediterranean, plant-based, high protein, high fibre, light, gluten-free. The Food diary keeps calories and macros per day, with a 7-day chart.
