1. Pat fish fillets dry with paper towel. Season with salt and pepper, then top each fillet with 1 sprig parsley, 1 sprig dill and 1 slice of lemon. Place 2 fillets, side by side, into a sous vide bag (18 cm x 16.5 cm - see Tips) and add 1 tablespoon of the oil. Seal using a vacuum sealer as per manufacturer’s instructions (see Tips). Repeat with another sous vide bag and remaining fillets, parsley, dill, oil and lemon slices. 
2. Insert blade cover. Place water into mixing bowl and start Kettle/50°C. 
3. Place sealed bags with fillets into mixing bowl, ensuring water covers bags and there is space between them for water to circulate. Start Sous-vide 45 min/50°C. 
4. Carefully remove bags using tongs. Remove from bags. Garnish with parsley and dill.  Serve with seasonal vegetables and sauce.

TIP 

• If you do not have a vacuum sealer, use the water displacement method: Fill a large container or bowl with water. Place 2 portions, side by side, into a snap lock bag and seal, leaving a gap of approx. 3 cm still open. Slowly submerge bag into the water (pressure from the water will force the air out), sealing bag closed just before it is completely submerged. We recommend using high quality snap lock bags. Look for bags made without BPA (Bisphenol A), which are widely available from major retailers. Polythene bags are not suitable for cooking food.
