# Scaling Yields and Editing Recipes

Cook:RE makes it easy to adjust batch sizes and customize recipe ingredients, steps, or metadata directly on your iPhone.

## Scaling Servings and Batch Sizes

When cooking for a larger crowd or scaling down a recipe for two:

1. Open the recipe in Cook:RE.
2. In the **Scaled** panel directly below the recipe title, use the **+** or **−** buttons to step the batch size up or down (e.g., `½×`, `1½×`, `2×`).
3. To enter an exact multiplier, tap the scaled yield text (e.g., `1× · 4 servings`) to type a custom factor.
4. All ingredient quantities and inline cooking amounts update automatically throughout the recipe.
5. Units adapt intelligently (e.g., scaling `2 tbsp` up by 4× displays as `½ cup` where appropriate).

## Editing Recipes Directly in the App

To modify any part of a recipe, tap the **`...`** (More options) button in the top navigation bar. Cook:RE provides three focused editors:

- **Recipe details:** Tap **Recipe details** to edit the recipe title, default yield or serving count, prep time, cook time, and source link. Tap **Save** to apply changes.
- **Edit ingredients:** Tap **Edit ingredients** to adjust any ingredient's quantity, unit, name, or preparation note. Drag the handle to reorder ingredients, or tap **Add Ingredient** to insert new items. Tap **Done** to save.
- **Edit steps:** Tap **Edit steps** to refine instruction text, add cooking durations or temperatures, reorder instructions, or insert new steps. Tap **Done** to save.
