+Feature: Recipe catalog
+  As a signed-in user
+  I want to browse, create and manage recipes
+  So that the household can plan meals from a shared catalog
+
+  Scenario: A visitor without a session cannot browse the catalog
+    When I request the recipe catalog
+    Then the response status should be 401
+    And the response error code should be "NOT_AUTHENTICATED"
+
+  Scenario: A signed-in user creates a recipe with an ingredient and a step
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    When I create a recipe named "Ratatouille" with ingredient "Tomate" and step "Couper les légumes"
+    Then the response status should be 201
+    And the created recipe should have ingredient "Tomate" and step "Couper les légumes"
+
+  Scenario: Creating a recipe with an unknown ingredient is rejected
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    When I create a recipe named "Ratatouille" with unknown ingredient id 999999 and step "Couper les légumes"
+    Then the response status should be 404
+    And the response error code should be "INGREDIENT_NOT_FOUND"
+
+  Scenario: A signed-in user sees their own recipe in the "perso" tab
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    And a recipe named "Ratatouille" already exists with ingredient "Tomate" and step "Couper les légumes"
+    When I request the recipe catalog tab "perso"
+    Then the response status should be 200
+    And the recipe catalog response should include "Ratatouille"
+
+  Scenario: A signed-in user favorites a recipe and finds it in the "favoris" tab
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    And a recipe named "Ratatouille" already exists with ingredient "Tomate" and step "Couper les légumes"
+    When I favorite the recipe named "Ratatouille"
+    And I request the recipe catalog tab "favoris"
+    Then the response status should be 200
+    And the recipe catalog response should include "Ratatouille"
+
+  Scenario: Only a recipe's author can edit it
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    And a public recipe named "Ratatouille" already exists with ingredient "Tomate" and step "Couper les légumes"
+    And a profile already exists with email "bob@example.com" and password "correct-horse-battery-staple"
+    And the second user logs in with email "bob@example.com" and password "correct-horse-battery-staple"
+    When the second user tries to modify the recipe named "Ratatouille"
+    Then the second user's response status should be 403
+    And the second user's response error code should be "NOT_RECIPE_AUTHOR"
+
+  Scenario: Deleting a recipe still used by a planning item is rejected
+    Given a profile already exists with email "alice@example.com" and password "correct-horse-battery-staple"
+    And I log in with email "alice@example.com" and password "correct-horse-battery-staple"
+    And a recipe named "Ratatouille" already exists with ingredient "Tomate" and step "Couper les légumes"
+    And my household has a planning that uses the recipe named "Ratatouille"
+    When I delete the recipe named "Ratatouille"
+    Then the response status should be 409
+    And the response error code should be "RECIPE_IN_USE"
