Hey there! I’ve dealt with tricky recipe site scrapes before—let’s get those ingredients pulled for your collection.

First, let’s break down why targeting those article.ingredients blocks might be failing:

• Basic requests get blocked: Many sites flag unmodified requests calls as bots, so you need to mimic a real browser.
• Dynamic content loading: The ingredients might load after the initial page via JavaScript, meaning static scrapers won’t pick them up right away.

Solution 1: Static Scraping with Proper Headers #

If the ingredients are in the raw HTML (sometimes they are, even if it feels dynamic), adding a user-agent header can bypass basic bot detection. Here’s a Python example using requests and BeautifulSoup:

import requests
from bs4 import BeautifulSoup

url = "https://www.koket.se/halloumigryta-med-tomat-linser-och-chili"
# Mimic a Chrome browser request
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36"
}

response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, "html.parser")

# Target both article blocks with the 'ingredients' class
ingredients_blocks = soup.find_all("article", class_="ingredients")

# Extract and print the ingredients from each block
for idx, block in enumerate(ingredients_blocks, 1):
    print(f"Ingredients Block {idx}:\n")
    # Clean up the text to make it readable
    clean_ingredients = block.get_text(strip=True, separator="\n")
    print(clean_ingredients + "\n")

Solution 2: Dynamic Scraping with Selenium (for JS-Loaded Content) #

If the ingredients don’t show up in the raw HTML, you’ll need to let JavaScript finish loading the page. Selenium mimics a real browser to handle this:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

url = "https://www.koket.se/halloumigryta-med-tomat-linser-och-chili"

# Initialize Chrome driver (make sure you have ChromeDriver installed)
driver = webdriver.Chrome()
driver.get(url)

# Wait up to 10 seconds for the ingredients blocks to load
wait = WebDriverWait(driver, 10)
ingredients_blocks = wait.until(EC.presence_of_all_elements_located((By.CLASS_NAME, "ingredients")))

# Extract and print the content
for idx, block in enumerate(ingredients_blocks, 1):
    print(f"Ingredients Block {idx}:\n")
    print(block.text.strip() + "\n")

driver.quit()

Quick Tips: #

• Always check the site’s robots.txt (you can find it at https://www.koket.se/robots.txt) to confirm personal-use scraping is allowed.
• Add small delays (time.sleep(2)) between requests if you scrape multiple pages to avoid getting blocked.
• If the class name ever changes, re-inspect the element in your browser’s dev tools to update your selector.
