# Cooking Operations

The cooking endpoints transform prepared ingredients into sauces and cooked products.

## Simmering

### POST /v1/cook/simmer

Simmer ingredients into a sauce. This is the primary way to turn sliced tomatoes into pizza sauce.

```python
import requests

API_BASE = "https://api.tomatopy.pizza/v1"
HEADERS = {
    "Content-Type": "application/json",
    "X-API-Key": "your-api-key",
    "X-Session-ID": "your-session-id"
}

# Simmer sliced tomatoes into sauce
response = requests.post(f"{API_BASE}/cook/simmer", headers=HEADERS, json={
    "ingredients": [
        {"id": "slc_def456", "name": "tomato", "amount": 400, "unit": "g"},
        {"id": "generic", "name": "garlic", "amount": 3, "unit": "cloves"},
        {"id": "generic", "name": "basil", "amount": 10, "unit": "leaves"}
    ],
    "temperature": 100,
    "duration": "30m"
})
sauce = response.json()

print(sauce["id"])           # "sce_jkl012"
print(sauce["sauce_quality"])  # "optimal"
```

#### Request Body

| Field         | Type    | Required | Description                                                   |
| ------------- | ------- | -------- | ------------------------------------------------------------- |
| `ingredients` | array   | yes      | List of ingredients, each with `id`, `name`, `amount`, `unit` |
| `temperature` | integer | yes      | Temperature in Celsius                                        |
| `duration`    | string  | yes      | Duration (e.g., "30m", "1h", "45m")                           |

#### Ingredient Object

| Field    | Type   | Required | Description                                               |
| -------- | ------ | -------- | --------------------------------------------------------- |
| `id`     | string | yes      | ID from a previous endpoint (e.g., sliced tomato ID)      |
| `name`   | string | yes      | Ingredient name                                           |

| `unit`   | string | yes      | Unit of measurement (e.g., "g", "ml", "cloves", "leaves") |

## Ingredient Requirements

{% hint style="warning" %}
**Raw tomato IDs silently degrade sauce quality.** Tomatoes must be sliced via `/tomato/slice` before being passed to `/cook/simmer`. The API will not return an error if you pass raw tomato IDs, but the resulting sauce quality will be significantly lower.
{% endhint %}

### Correct Flow: Slice First, Then Simmer

```python
# Step 1: Acquire a tomato
response = requests.post(f"{API_BASE}/tomato/acquire", headers=HEADERS, json={
    "variety": "San Marzano",
    "ripeness": 0.9,
    "weight": 400
})
tomato = response.json()

# Step 2: Slice the tomato (REQUIRED for quality)
response = requests.post(f"{API_BASE}/tomato/slice", headers=HEADERS, json={
    "tomato_ids": [tomato["id"]],
    "method": "dice",
    "size": "medium",
    "consistency": "uniform"
})
sliced = response.json()

# Step 3: Simmer the SLICED tomato
response = requests.post(f"{API_BASE}/cook/simmer", headers=HEADERS, json={
    "ingredients": [
        {"id": sliced["id"], "name": "tomato", "amount": 400, "unit": "g"}
    ],
    "temperature": 100,
    "duration": "30m"
})
good_sauce = response.json()
print(good_sauce["sauce_quality"])  # "optimal"
```

### Incorrect Flow: Raw Tomato Directly to Simmer

```python
# WRONG: Skipping the slice step
response = requests.post(f"{API_BASE}/tomato/acquire", headers=HEADERS, json={
    "variety": "San Marzano",
    "ripeness": 0.9,
    "weight": 400
})
tomato = response.json()

# Passing raw tomato ID directly to simmer -- NO ERROR, but quality degrades
response = requests.post(f"{API_BASE}/cook/simmer", headers=HEADERS, json={
    "ingredients": [
        {"id": tomato["id"], "name": "tomato", "amount": 400, "unit": "g"}
    ],
    "temperature": 100,
    "duration": "30m"
})
bad_sauce = response.json()
print(bad_sauce["sauce_quality"])  # "degraded" -- silently degraded!
```

## Roasting

### POST /v1/cook/roast

Roast ingredients for a different flavor profile. Roasting works well for creating deeper, caramelized flavors.

```python
# Roast tomatoes and garlic
response = requests.post(f"{API_BASE}/cook/roast", headers=HEADERS, json={
    "ingredients": [
        {"id": sliced["id"], "name": "tomato", "amount": 400, "unit": "g"},
        {"id": "generic", "name": "garlic", "amount": 6, "unit": "cloves"}
    ],
    "temperature": 200,
    "duration": "45m"
})
roasted = response.json()

print(roasted["id"])       # "rst_mno345"
print(roasted["type"])           # "roasted"
```

#### Request Body

| Field         | Type    | Required | Description                                 |
| ------------- | ------- | -------- | ------------------------------------------- |
| `ingredients` | array   | yes      | List of ingredients (same format as simmer) |
| `temperature` | integer | yes      | Temperature in Celsius                      |
| `duration`    | string  | yes      | Duration (e.g., "45m", "1h")                |

## Choosing Between Simmer and Roast

| Aspect      | Simmer               | Roast                     |
| ----------- | -------------------- | ------------------------- |
| Temperature | 80-120 C             | 150-250 C                 |
| Duration    | 20m-2h               | 30m-1h                    |
| Result      | Smooth, liquid sauce | Concentrated, caramelized |
| Best for    | Classic marinara     | Deep, rich flavors        |

## Error Handling

```python
# Handle validation errors
response = requests.post(f"{API_BASE}/cook/simmer", headers=HEADERS, json={
    "ingredients": [],  # Empty ingredients list
    "temperature": 100,
    "duration": "30m"
})

if response.status_code == 400:
    error = response.json()
    print(f"Error: {error['message']}")  # "Ingredients list cannot be empty"
```

## Best Practices

1. **Always Slice Tomatoes First**

   Never pass raw tomato IDs to cooking endpoints. The quality degradation is silent and significant.
2. **Use Appropriate Temperatures**

   Simmering should be 80-120 C. Roasting should be 150-250 C. Values outside these ranges may produce unexpected results.
3. **Check the Quality Field**

   ```python
   sauce = response.json()
   if sauce["sauce_quality"] == "degraded":
       print("Warning: Degraded sauce. Did you slice the tomatoes first?")
   ```

## Endpoint Reference

| Endpoint          | Method | Description                   |
| ----------------- | ------ | ----------------------------- |
| `/v1/cook/simmer` | POST   | Simmer ingredients into sauce |
| `/v1/cook/roast`  | POST   | Roast ingredients             |
